Phys. 16 043005). Read the full article in New Journal http://iopscience.iop.org/1367-2630/16/4/043005/article. GENERAL SCIENTIFIC SUMMARY Introduction and background. Quantum key distribution (QKD) offers a new means for providing data security without being compromised by future breakthroughs in our computational capabilities. QKD has been demonstrated on experimental and commercial platforms over distances exceeding 200 km. Nevertheless, by relying on single photons for its communications, it has been challenging to reach longer distances. One possible approach to long-distance QKD is to rely on so-called quantum repeaters, which typically use quantum memories to store the state of single photons. Building quantum memories that meet all the required criteria is, however, demanding. This does not imply that a quasi-repeater system, with a clear advantage over direct QKD links, cannot be demonstrated soon. The current paper proposes such a scheme, where, by using certain quantum memories, one can devise QKD systems that outperform existing QKD systems. Main results. Our proposed schemes have milder requirements on the quantum memory modules, and hence offer a first step towards a more feasible solution for QKD over distances up to around 500 km. If implemented, they will be the first examples of functional QKD systems in which the quantum memories offer a clear advantage. Our analysis, which accounts for many relevant experimental parameters, shows that the technology for the quantum memories to be used in our scheme is almost there, and thus an experimental demonstration is expected soon. Wider implications. The architecture we use in our scheme is compatible with future publicly available quantum-classical communication networks. A slight adjustment will then be needed once the quantum repeaters are in full swing.

Device Independence: A New Paradigm for Randomness Manipulation? - Thomas Vidick
 
01:19:33
Thomas Vidick Massachusetts Institute of Technology April 1, 2013 A trusted source of independent and uniform random bits is a basic resource in many computational tasks, such as cryptography, game theoretic protocols, algorithms and physical simulations. Implementing such a source presents an immediate challenge: how can one certify whether one has succeeded? i.e. suppose someone were to claim that a particular device outputs a uniformly random n-bit string; is there a feasible test to verify that claim? This seems like an impossible task: since the device must output each n-bit string with equal probability there is no basis on which to reject any particular output in favor of any other. Ideas originating in the study of nonlocality in quantum mechanics suggest a remarkable solution to this conundrum: a random number generator whose output is certifiably random in the sense that if the output passes a simple statistical test, and a no-signaling condition is met between the two boxes in the randomness generating device, then even a quantum skeptic (viz Einstein's famous quote ``God does not play dice with the Universe''), would be convinced that the output is truly random. Partially dropping the skeptic's hat, I will show how the same ideas can be used to obtain a protocol for key distribution whose security, although it relies on the correctness of quantum mechanics, does not require any assumption on the nature of the quantum mechanical devices used in the protocol. In particular, security of the generated key is guaranteed even if the devices are faulty or even have been handed over to the users by a malicious, computationally unbounded, adversary. These results suggest a powerful paradigm of "device independence" enabling previously impossible tasks under minimal assumptions. Based on joint work with Umesh Vazirani.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Identity-based cryptography is a type of public-key cryptography in which a publicly known string representing an individual or organization is used as a public key. The public string could include an email address, domain name, or a physical IP address. The first implementation of identity-based signatures and an email-address based public-key infrastructure (PKI) was developed by Adi Shamir in 1984, which allowed users to verify digital signatures using only public information such as the user's identifier. Under Shamir's scheme, a trusted third party would deliver the private key to the user after verification of the user's identity, with verification essentially the same as that required for issuing a certificate in a typical PKI. Shamir similarly proposed identity-based encryption, which appeared particularly attractive since there was no need to acquire an identity's public key prior to encryption. However, he was unable to come up with a concrete solution, and identity-based encryption remained an open problem for many years. The first practical implementations were finally devised by Sakai in 2000, and Boneh and Franklin in 2001. These solutions were based on bilinear pairings. Also in 2001, a solution was developed independently by Clifford Cocks. Identity-based systems allow any party to generate a public key from a known identity value such as an ASCII string. A trusted third party, called the private key generator (PKG), generates the corresponding private keys. To operate, the PKG first publishes a master public key, and retains the corresponding master private key (referred to as master key). Given the master public key, any party can compute a public key corresponding to the identity ID by combining the master public key with the identity value. To obtain a corresponding private key, the party authorized to use the identity ID contacts the PKG, which uses the master private key to generate the private key for identity ID. Identity-based systems have a characteristic problem in operation. Suppose Alice and Bob are users of such a system. Since the information needed to find Alice's public key is completely determined by Alice's ID and the master public key, it is not possible to revoke Alice's credentials and issue new credentials without either (a) changing Alice's ID (usually a phone number or an email address which will appear in a corporate directory); or (b) changing the master public key and re-issusing private keys to all users, including Bob. This limitation may be overcome by including a time component (e.g. the current month) in the identity.

The Kish Key Distribution System: A classical alternative to quantum key distribution
 
48:58
- By: Lachlan J. Gunn, School of Electrical and Electronic Engineering, The University of Adelaide, Australia - Date: 2014-10-29 14:30:00 - Description: Public key cryptography has raised cryptography from a curiosity, useful mainly to governments, to its status as a pillar for modern communications. But above this magnificent throne hangs a sword of Damocles in the form of quantum computing, motivating the development of new approaches. Some have turned to physics, developing systems with security guarantees based on natural laws. The most popular is Quantum Key Distribution, but its complexity has spurred the development of alternatives. We examine KKD, an entirely electronic system, charting the attacks and countermeasures that have been introduced since its introduction in 2006.

The best known example of quantum cryptography is quantum key distribution which offers an information-theoretically secure solution to the key exchange problem. "With quantum computing, we are on the verge of another technological leap that could be as deep and transformative. Quantum key distribution systems are already commercially available, but have only limited uses as they employ attenuated lasers and have a range of up to 300km in optical fibre cables. Quantum key distribution (QKD) uses individual photons for the exchange of cryptographic key data between two users, where each photon represents a single bit of data. A technique called quantum cryptography can, in principle, allow you to encrypt a message in such a way that it would never be read by anyone whose eyes it isn't for.

Is the Universe Actually a Giant Quantum Computer?
 
23:13
According to professor Seth Lloyd, the answer is yes: "Everything in the universe is made of chunks of information called bits." A researcher in Mechanical Engineering at MIT, Lloyd is one of the leaders in the field of quantum information. Decades ago, the feasibility of developing quantum computing devices was challenged. Now, as quantum computation is producing actual technologies, we are only left to wonder—what kind of applications will it provide us with next? To begin understanding if the universe is a giant quantum computer—that is, a computer that operates using the principles of quantum mechanics—we must first understand the building blocks. What is information? According to Lloyd, everything in the universe is made of chunks of information called bits. These are the zeroes and ones that an engineer uses as the building blocks of computer software. Atoms themselves are also bits of information. Tiny particles such as electrons, whose positions and velocities we cannot know for certain, are described by quantum mechanics. We can only give an estimate as to where an electron might be, and how fast it is moving. Before we make the measurement, the electron could be in any position, at the same time. In a regular computer, information is encoded as bits interpreted as either 0 or 1. In a quantum computer, this information comes in slightly different variety – quantum bits, or “qubits”. These qubits can be in one state, in another, or somewhere in between. A classical computer can read only one bit at a time, while a quantum computer will read all possible combinations. This means that quantum computers can give us a completely new and incredibly fast means of computing, such as factoring large numbers or evaluating extremely complex algorithms used for data analysis in finance, science, or cryptography. Just like a quantum computer, physical processes involve the exchange and processing of information. Ed Fredkin first proposed that the Universe could be a computer in the 1960’s, as well as Konrad Zuse who came up with the idea independently. In their view, the Universe could be a type of computer called a cellular automaton, which describes a dynamic system that is broken apart into black and white grids, in which cells gather information from the surrounding cells on whether or not to change color. This is similar to the way a line or moving colony of ants might share information between each other about their surroundings, signaling to each other whether or not to follow a food trail. However, this initial analogy to such sharing of information turned out to be not quite accurate. Regular computers are not so good at simulating quantum systems that do not follow the “yes” or “no” kind of signals, since quantum systems can have mixed signals! These are called the superposition of states, and can only be simulated by a quantum rather than classical computer. Since the universe itself is best described by quantum mechanics, Lloyd suggests that “quantum computing allows us to understand the universe in its own language.” Physicists are not the only ones keen to reap the benefits of quantum computing; companies like IBM and Canadian D-wave as well as agencies like the CIA and NSA are also investing heavily in quantum computation research. The universe, however, might have already invested in a quantum computer. After all, information is processed in a very quantum mechanical way both on a tiny and large scale. The efficiency of these processes in our universe may very well suggest its true nature—of a quantum kind.

The Quantum Conspiracy: What Popularizers of QM Don't Want You to Know
 
01:03:43
Google Tech Talk January 6, 2011 Presented by Ron Garret. ABSTRACT Richard Feynman once famously quipped that no one understands quantum mechanics, and popular accounts continue to promulgate the view that QM is an intractable mystery (probably because that helps to sell books). QM is certainly unintuitive, but the idea that no one understands it is far from the truth. In fact, QM is no more difficult to understand than relativity. The problem is that the vast majority of popular accounts of QM are simply flat-out wrong. They are based on the so-called Copenhagen interpretation of QM, which has been thoroughly discredited for decades. It turns out that if Copenhagen were true then it would be possible to communicate faster than light, and hence send signals backwards in time. This talk describes an alternative interpretation based on quantum information theory (QIT) which is consistent with current scientific knowledge. It turns out that there is a simple intuition that makes almost all quantum mysteries simply evaporate, and replaces them with an easily understood (albeit strange) insight: measurement and entanglement are the same physical phenomenon, and you don't really exist.

Title: Measurement-Assisted Quantum Communication in Spin Channels Speaker: Dr. Abolfazl Bayat Ph.D., Research Associate University College London Abstract: Measurements are performed through interaction with classical macroscopic apparatus on quantum systems. The general belief is that measurement destroys the quantumness of the system through wave function collapse, In contrast to this general perspective, here, we show that measurements can be exploited for enhancing the performance of quantum communication in spin chains. I try to cover some recent proposals for such schemes in which performing measurement enhances the quality of transport and counters the effect of dephasing.

Overview of Quantum Technology Landscape: Quantum Base. Presented by Phillip Speed
 
07:30
Presented by Phillip Speed, Co-founder of Quantum Base http://quantumbase.com/ QB provides simple, small, provably secure quantum security devices that can fit onto any surface or within any device. Quantum Base - a world leader in Quantum Security; the solutions of the future will be fortified by our world leading innovation. We have invented a suite of products providing authentication, identification and security across communications networks, devices and products. Our quantum identities (Q-ID’s) use the unique arrangements of atoms and the imperfections in these structures to create devices, which are simple, small and cheap. They have the highest bit density, the best integration potential and use the least amount of resources possible; furthermore they can be easily inserted into existing standard CMOS or III-V manufacturing processes. The products can be used independently to provided authentication and identification, or can be deployed within existing solution architectures, harnessing the benefits that quantum technologies bring. They offer the ultimate in provable security, have low power usage, the smallest footprint possible, have low bandwidth requirements and all without the need for large scale computations, the accompanying infrastructure or processing requirements. Physically unclonable functions (PUF’s) are an emerging technology for the secure provision of public (security) keys. They provide unique information derived from random physical characteristics, and have many advantages over conventional passwords or software keys in public key cryptography. But despite their obvious advantages, existing classical PUF technologies are often expensive, large, can be difficult to implement or are potentially susceptible to sophisticated attacks. The electronic solution can be embedded in a microprocessor to provide a unique fingerprint for authentication and encryption, and is suitable for direct integration into simple semiconductor devices. The optical solution can be read using a standard smart phone and a cheap filter. The optical device uses two dimensional “graphene like” sheets, and because each device has a unique identity, each one can be addressed individually and directly using Internet or new media technologies. In addition to the suite outlined above, we have developed a Quantum lock, and we are continuing to build a portfolio of products that can be used independently or together in networked environments, using cutting edge quantum physics and two dimensional “graphene like” materials, that use off the shelf equipment, operating at room temperature and on a Nano scale, that has no incremental cost once volume production is achieved. Global product Authentication Figures released in 2016 by the OECD and the EU Intellectual Property Office state that imports of all counterfeit and pirated goods globally are worth nearly half a trillion U.S. dollars; across such diverse verticals as automotive, aerospace, fashion, sports, technology, foodstuffs, and pharmaceuticals. Those technologies deemed to be at the heart of stopping counterfeiting are not working. In a world’s first, Quantum Base has developed a Quantum physically unclonable function (Q PUF) the quantum identity or (Q-ID) using “Quantum Mechanical Tunnelling”. With this we have: • Created unique physical quantum ‘signatures’, which can be read with a standard smart phone and cheap filter, this is at the core of our identification and authentication technology. • Overcome the security failings of existing security systems such holograms, PUF’s such as SRAM or Delay PUFs, which rely on measurement of physical properties in existing circuitry, rendering them susceptible to sophisticated attacks. • Developed a PUF based device, our Q-IDs, which cannot be copied, cloned or simulated: the laws of quantum physics guarantee this. Global Data Security: In one example of data security issues, Business Insider (2017) suggests that the number of IoT devices could top 24 billion globally by 2020. McKinsey advocate this market to be valued at $6bn, while CISCO state this figure could be closer to $14bn and 50 billion devises. Either way, the Vormetric Data Threat report (2016) concluded that the protection of sensitive data ranked as the top concern (36%) among IoT enterprises. Regardless of this meteoric growth in IoT, there is still no existing 100% security protection for this mass connectivity across business, government and individual consumers (Business Insider 2017). To counter this, we deploy our suite of products: the Q-ID’s or Quantum Identities, various Quantum Random Number Generators (RNG) and RNG+, and Quantum Lock. Quantum Base, securing your connected future, providing provable security, guaranteed by the laws of physics.

Umesh Vazirani (University of California, Berkeley), Certifiable Quantum Dics
 
01:05:56
Rajeev Motwani Distinguished Seminar April 19th, 2012 Stanford, CA Title: Certifiable Quantum Dice. Speaker: Umesh Vazirani (University of California, Berkeley) Abstract: A source of independent and uniform random bits is a basic resource in many computational tasks, such as cryptography, game theoretic protocols, algorithms and physical simulations. In the classical world it is impossible to construct a random number generator whose output can be certified to be a uniformly random n-bit string, since there seems to be no basis on which to reject any particular output in favor of any other. Quantum mechanics allows for a remarkable random number generator: its output is certifiably random in the sense that if the output passes a simple statistical test, and a no-signaling condition is met between the two boxes in the randomness generating device (based, say, on the speed of light limit imposed by special relativity), even a quantum skeptic (viz Einstein's famous quote ``God does not play dice with the Universe''), would be convinced that the output is truly random, independent of the validity of quantum mechanics! Based on joint work with Thomas Vidick. Bio: Umesh Vazirani received his B.Tech. in computer science from MIT in 1981 and his Ph.D. in computer science from U.C. Berkeley in 1986. He is currently professor of computer science at U.C. Berkeley and director of BQIC - the Berkeley center for Quantum Information and Computation. Prof. Vazirani is a theoretician with broad interests in novel models of computation. He has done seminal work in quantum computation and on the computational foundations of randomness. He is the author of two books "An introduction to computational learning theory" with Michael Kearns and "Algorithms" with Sanjoy Dasgupta and Christos Papadimitriou.
HotSpot Episode 92: Flying Inventory Robots Keep Track of Products

--- Quality Assurance The BMW Group is testing out the Google Glass to see if it could improve and accelerate the workflows in quality assurance. The wearable technology allows workers to take photos or videos as a means to document potential deviations, providing a better, faster and clearer way to analyze and correct these later on. The purpose of the pilot project is to improve the communication between quality testers at the analysis center of the pre-series production on the one hand and the development engineers on the other. --- Quantum Memory Storage Quantum computers or quantum cryptography will never become prevalent technologies without memory systems that are able to manipulate quantum information easily and effectively. The Faculty of Physics at the University of Warsaw has recently made inroads into popularizing quantum information technologies by creating an atomic memory with outstanding parameters and an extremely simple construction. A glass chamber with rubidium-coated sides and filled with a noble gas makes up the main element of the memory device. When the tube is heated gently, rubidium pairs fill the inside, with the noble gas restricting their movement and thereby reducing noise. When quantum information is stored in such a memory, photons from the laser beam “imprint” quantum states on many rubidium atoms. Other photons are emitted at the same time; their detection confirms that the information has been saved. Information stored in the memory can then be retrieved using another specially selected laser pulse. --- New ART-Fi Agreement American Certification Body (ACB) has announced an agreement with ART-FI and EMTREK to market and service the ART-MAN SAR test bench to Chinese mobile and laptop manufacturers. ART-MAN is a new SAR (Specific Absorption Rate) testing solution that uses cutting-edge technologies to make SAR testing more accurate, faster, and easier to carry-out for the testing engineers and antenna designers. --- Flying Inventory Robots The goal of the InventAIRy Project at the Fraunhofer Institute for Material Flow and Logistics IML in Dortmund, is to automatically localize and record existing inventories with the aid of flying robots. With the InventAIRy solution, radio chips remain a fixed position and an antenna is moved by its integration into a flying autonomous robot that moves throughout a warehouse, and track through barcodes and RFID tags. The advantage: These robots act independent of ground-based obstructions. Furthermore, they can move in any direction and see into hard-to-reach places, such as tall storage shelves.

The Era of Teleporting Information Has Begun
 
04:49
WELCOME! 😃 SUBSCRIBE ► http://bit.ly/2fu2wQF | ★ PREVIOUS VIDEOS ► http://bit.ly/2vHZRJk | ★ PLAYLISTS ► http://bit.ly/2ihjMJZ ********************************** The Era of Teleporting Information Has Begun We are only one step away from admitting that the world around us is just an illusory product of our mind. Quantum physics is largely revealing that our world is not what we think it is and teleportation of information is now a reality of that world. Quantum communication over long distances is integral to information security and has been demonstrated in free space with two-dimensional states, recently over distances exceeding 1200 km between satellites. But using only two states reduces the information capacity of the photons, so the link is secure but slow. To make it secure and fast requires a higher-dimensional alphabet, for example, using patterns of light, of which there are an infinite number. One such pattern set is the orbital angular momentum (OAM) of light. Increased bit rates can be achieved by using OAM as the carrier of information. However, such photon states decay when transmitted over long distances, for example, due to mode coupling in fibre or turbulence in free space, thus requiring a way to amplify the signal. Unfortunately such “amplification” is not allowed in the quantum world, but it is possible to create an analogy, called a quantum repeater, akin to optical fibre repeaters in classical optical networks. An integral part of a quantum repeater is the ability to entangle two photons that have never interacted -- a process referred to as “entanglement swapping”. This is accomplished by interfering two photons from independent entangled pairs, resulting in the remaining two photons becoming entangled. This allows the establishment of entanglement between two distant points without requiring one photon to travel the entire distance, thus reducing the effects of decay and loss. It also means that you don’t have to have a line of sight between the two places. An outcome of this is that the information of one photon can be transferred to the other, a process called teleportation. Like in the science fiction series, Star Trek, where people are “beamed” from one place to another, information is “teleported” from one place to another. If two photons are entangled and you change a value on one of them, then other one automatically changes too. This happens even though the two photons are never connected and, in fact, are in two completely different places. In this latest work, the team performed the first experimental demonstration of entanglement swapping and teleportation for orbital angular momentum (OAM) states of light. They showed that quantum correlations could be established between previously independent photons, and that this could be used to send information across a virtual link. Importantly, the scheme is scalable to higher dimensions, paving the way for long-distance quantum communication with high information capacity. Background Present communication systems are very fast, but not fundamentally secure. To make them secure researchers use the laws of Nature for the encoding by exploiting the quirky properties of the quantum world. One such property is entanglement. When two particles are entangled they are connected in a spooky sense: a measurement on one immediately changes the state of the other no matter how far apart they are. Entanglement is one of the core resources needed to realise a quantum network... ********************************** ★ SUBSCRIBE TO MY CHANNEL TO BE INFORMED FOR NEW DAILY VIDEOS!
