Simple is beautiful in quantum computing
Quantum computers use electron spin orientation at a defect site in diamond to store information. The electron spin can be up (+1), down (-1), or anything in between. The spin (left, red arrow) is represented as a vector on a sphere. To change the spin from Position 1 to 2 normally requires two separate optical pulses. However, here a particular single pulse has accomplished the same electronic tr
Black holes, curved spacetime and quantum computing
Black holes, curved spacetime and quantum computing by Elsevier Rotating black holes and computers that use quantum-mechanical phenomena to process information are topics that have fascinated science lovers for decades, but even the most innovative thinkers rarely put them together. Now, however, theoretical physicist Ovidiu Racorean from the General Direction of Information Technology, Bucharest,
Microsoftが量子コンピューティングの競争に参戦
Microsoftは同社のIgniteカンファレンスで、量子コンピューティングプラットフォームのプレビューを新たに発表するとともに、近年の素粒子物理学の進歩を活用したトポロジカル量子コンピュータ(topological quantum computer)の開発計画を公開した。 Microsoft Quantum Previewには量子コンピューティングシミュレータと、Visual Studioに統合された量子コンピューティング用の新プログラム言語が含まれている。Microsoftによると、同社のトポロジカルキュビットは従来よりも長く、一貫性を持って、少ないエラーで動作する。 Microsoftは、現在まだ開発の初期段階にある、スケーラブルな汎用トポロジカル量子コンピューティングをも視野に入れている。同社CEOのSatya Nadella氏は、開発チームから4名が参加した仮想パネルセッション
Superconducting qubits can function as quantum engines
Superconducting qubits can function as quantum engines by Lisa Zyga , Phys.org In this double quantum well system, the left well remains static while the right one oscillates, allowing work to be performed on the system. Credit: Sachtleben et al. ©2017 American Physical Society (Phys.org)—Physicists have shown that superconducting circuits—circuits that have zero electrical resistance—can function
Scientists pinpoint the singularity for quantum computers
Dr Anthony Laing, Chris Sparrow and Alex Neville. Credit: University of Bristol Researchers from the University of Bristol have discovered that super-powerful quantum computers, which scientists and engineers across the world are racing to build, need to be even more powerful than previously thought before they can beat today's ordinary PCs. Quantum computers are a new type of machine that operate
