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.
