Emerging Trends Indigitalauthentication

Authors: Prajwal S Nayak
Comments: 5 Pages.

This manuscript attempts to shed the light on the authentication systems’ evolution towards Multi-factor Authentication (MFA) from traditional text based password systems. The evolution of authen-tication systems is commensurate with that of security breaching techniques. While many strongauthentication products, such as multi-factor authentication (MFA), single sign-on (SSO), biometricsand privileged access management (PAM), have existed for a long time, the constant deluge ofdata breaches and password database leaks has re-illustrated the weakness in many authenticationparadigms. As a result, the industry is both re-thinking they way we approach authentication andmaking efforts to simplify previously complex or expensive authentication technologies for the everyhuman being.

Potential for Quantum Computing

Authors: George Rajna
Comments: 65 Pages.

A joint team of scientists at the University of California, Riverside, and the Massachusetts Institute of Technology is getting closer to confirming the existence of an exotic quantum particle called Majorana fermion, crucial for fault-tolerant quantum computing—the kind of quantum computing that addresses errors during its operation. [39] A recent study led by Princeton University researchers, in collaboration with University of Maryland and IBM, explored the architectural design of quantum computers (QC). [38] Science at Princeton, identify three key difficulties in debugging quantum programs, and evaluate their solutions in addressing those difficulties. [37] Researchers at the University of Chicago published a novel technique for improving the reliability of quantum computers by accessing higher energy levels than traditionally considered. [36] An international team of researchers has taken an important step towards solving a difficult variation of this problem, using a statistical approach developed at the University of Freiburg. [35] Storing information in a quantum memory system is a difficult challenge, as the data is usually quickly lost. At TU Wien, ultra-long storage times have now been achieved using tiny diamonds. [34] Electronics could work faster if they could read and write data at terahertz frequency, rather than at a few gigahertz. [33] A team of researchers led by the Department of Energy's Oak Ridge National Laboratory has demonstrated a new method for splitting light beams into their frequency modes. [32] Quantum communication, which ensures absolute data security, is one of the most advanced branches of the "second quantum revolution". [31] Researchers at the University of Bristol's Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information.

Architectural Design of Quantum Computers

Authors: George Rajna
Comments: 63 Pages.

A recent study led by Princeton University researchers, in collaboration with University of Maryland and IBM, explored the architectural design of quantum computers (QC). [38] In the paper titled "Statistical Assertions for Validating Patterns and Finding Bugs in Quantum Programs," Huang and Margaret Martonosi, a professor of Computer Science at Princeton, identify three key difficulties in debugging quantum programs, and evaluate their solutions in addressing those difficulties. [37] Researchers at the University of Chicago published a novel technique for improving the reliability of quantum computers by accessing higher energy levels than traditionally considered. [36] An international team of researchers has taken an important step towards solving a difficult variation of this problem, using a statistical approach developed at the University of Freiburg.

Quantum Supremacy: Reality or Myth?

Authors: Victor Paromov
Comments: 2 Pages.

Calculation supremacy is expected for quantum computers operating with about 50 qubits. However, in case the non-classical spacetime geometry-based theory (http://vixra.org/abs/1806.0181) of particle interactions is right, entanglement exists for the observer-bound coordinate systems only, thus requiring additional control. If so, quantum supremacy would be hardly achievable.

Polarization-Encryption Data Storage

Authors: George Rajna
Comments: 55 Pages.

This sensitivity to polarization depended on the direction of the incoming light; for instance, light in a specific direction prompted the arrays to produce binary images, whereas light in the opposite direction could reproduce grayscale photographs. [37] From books to floppy disks to magnetic memory, technologies to store information continue to improve. Yet threats as simple as water and as complex as cyberattacks can still corrupt our records. [36] Researchers at Rensselaer Polytechnic Institute have come up with a way to manipulate tungsten diselenide (WSe2)-a promising two-dimensional material-to further unlock its potential to enable faster, more efficient computing, and even quantum information processing and storage. [35] The human brain has amazing capabilities making it in many ways more powerful than the world's most advanced computers. [34] In 2017, University of Utah physicist Valy Vardeny called perovskite a "miracle material" for an emerging field of next-generation electronics, called spintronics, and he's standing by that assertion. [33] Scientists at Tokyo Institute of Technology proposed new quasi-1-D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons. [32] They do this by using "excitons," electrically neutral quasiparticles that exist in insulators, semiconductors and in some liquids. [31] Researchers at ETH Zurich have now developed a method that makes it possible to couple such a spin qubit strongly to microwave photons. [30] Quantum dots that emit entangled photon pairs on demand could be used in quantum communication networks. [29] Researchers successfully integrated the systems-donor atoms and quantum dots. [28] A team of researchers including U of A engineering and physics faculty has developed a new method of detecting single photons, or light particles, using quantum dots. [27]

[27] Recent research from Kumamoto University in Japan has revealed that polyoxometalates (POMs), typically used for catalysis, electrochemistry, and photochemistry, may also be used in a technique for analyzing quantum dot (QD) photoluminescence (PL) emission mechanisms. [26] Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. [25]

Deeper Understanding of Networks

Authors: George Rajna
Comments: 67 Pages.

Network functioning and dynamical properties have more and closer connections with higher-order network topological features, homogeneous substructures and topological invariants. [42] In recent years, the unique properties of linear optical systems have also inspired the development of computational complexity theory. [41] Multinational corporations, such as IBM and Google, are now building intermediate-size quantum computers with increasing number of quantum units or qubits. [40] Physicists at The City College of New York have used atomically thin two-dimensional materials to realize an array of quantum emitters operating at room temperature that can be integrated into next generation quantum communication systems. [39] Research in the quantum optics lab of Prof. Barak Dayan in the Weizmann Institute of Science may be bringing the development of such computers one step closer by providing the "quantum gates" that are required for communication within and between such quantum computers. [38] Calculations of a quantum system's behavior can spiral out of control when they involve more than a handful of particles. [37] Researchers from the University of North Carolina at Chapel Hill have reached a new milestone on the way to optical computing, or the use of light instead of electricity for computing. [36] The key technical novelty of this work is the creation of semantic embeddings out of structured event data. [35] The researchers have focussed on a complex quantum property known as entanglement, which is a vital ingredient in the quest to protect sensitive data. [34] Cryptography is a science of data encryption providing its confidentiality and integrity. [33] Researchers at the University of Sheffield have solved a key puzzle in quantum physics that could help to make data transfer totally secure. [32]

3-D Magnetic Interactions Computing

Authors: George Rajna
Comments: 66 Pages.

A new form of magnetic interaction which pushes a formerly two-dimensional phenomenon into the third dimension could open up a host of exciting new possibilities for data storage and advanced computing, scientists say. [42] Two researchers at Université de Sherbrooke, in Canada, have recently developed and trained neural belief-propagation (BP) decoders for quantum low-density parity-check (LDPC) codes.
