Verifying Quantum Computers Output

Authors: George Rajna
Comments: 94 Pages.

A team of researchers from the University of Innsbruck and the Austrian Academy of Sciences has developed a way to verify the output from one quantum computer by comparing it to the output of another quantum computer. [57] A new test to check if a quantum computer is giving correct answers to questions beyond the scope of traditional computing could help the first quantum computer that can outperform a classical computer to be realized. [56] In quantum computing, as in team building, a little diversity can help get the job done better, computer scientists have discovered. [55] Significant technical and financial issues remain towards building a large, fault-tolerant quantum computer and one is unlikely to be built within the coming decade. [54] Chemists at Friedrich Schiller University in Jena (Germany) have now synthesised a molecule that can perform the function of a computing unit in a quantum computer. [53] The research team developed the first optical microchip to generate, manipulate and detect a particular state of light called squeezed vacuum, which is essential for HYPERLINK "https://phys.org/tags/quantum/" quantum computation. [52] Australian scientists have investigated new directions to scale up qubits-utilising the spin-orbit coupling of atom qubits-adding a new suite of tools to the armory. [51] A team of international researchers led by engineers from the National University of Singapore (NUS) have invented a new magnetic device to manipulate digital information 20 times more efficiently and with 10 times more stability than commercial spintronic digital memories. [50] Working in the lab of Mikhail Lukin, the George Vasmer Leverett Professor of Physics and co-director of the Quantum Science and Engineering Initiative, Evans is lead author of a study, described in the journal Science, that demonstrates a method for engineering an interaction between two qubits using photons. [49] Researchers with the Department of Energy's Oak Ridge National Laboratory have demonstrated a new level of control over photons encoded with quantum information. [48]

Nano Antennas Data Transfer

Authors: George Rajna
Comments: 95 Pages.

Physicists from the University of Würzburg have converted electrical signals into photons and radiated them in specific directions using a low-footprint optical antenna that is only 800 nanometers in size. [58] Prospective digital data storage devices predominantly rely on novel fundamental magnetic phenomena. [57] Scientists at Linköping University have shown how a quantum computer really works and have managed to simulate quantum computer properties in a classical computer. [56] Scientists from the University of Bath, working with a colleague at the Bulgarian Academy of Sciences, have devised an ingenious method of controlling the vapour by coating the interior of containers with nanoscopic gold particles 300,000 times smaller than a pinhead.
