University of Bristol researchers efforts push quantum computer programming forward. This work helps overcome the challenge of precision-entanglement beyond the current single-qubit systems. Using CMOS-compatible photonic components and metal-oxide semi-conductors, their device has proven two-qubit operations with 93% (+/- 4.5%) efficiency. “Photonics is a promising platform for implementing universal quantum information processing. Its main challenges include precise control of massive circuits of linear optical components and effective implementation of entangling operations on photons.”
The University of Adelaide is reporting the ability to fire one billion electrons per second using quantum mechanics; repeatedly. This is a major step to “reliable, continuous, and consistent” electron flow using quantum mechanics, a ‘must have’ for quantum computing. Clicking image takes you to schematic’s abstract.
Tokyo Institute of Technology researchers have matched theory to observation and thus have achieved a “comprehensive understanding of the coherent control of coherent optical phonons.” The usefulness of which is geared toward quantum computing memory systems as well as materials science and superconductivity.
