Computers employ a variety of schemes to check whether a chunk of digital information–transmitted as a message, stored in a database, or functioning as a set of instructions–remains error-free. Such ...

IBM scientists today unveiled two critical advances towards the realization of a practical quantum computer. For the first time, they showed the ability to detect and measure both kinds of quantum ...

図2.13から分かるように、距離が3のコードワード間では、2ビットのエラーが起こると隣のコードワードを囲む1ビットエラーの球に入ってしまう。そして、受信されたデータに対してシンドロームを計算して訂正を行うと、 2ビットのエラーが起こったコード ...

Scientists have for the first time demonstrated improvement in quantum computers by using codes designed to detect and discard errors in the logic gates of such machines. The codes were applied to IBM ...

A preprint study by Quantiniuum claims a new error-detecting code was able to accurately simulate a hydrogen molecule and could help create more advanced quantum computers. A team of scientists claim ...

I, Brian Wang, interviewed Andrei Petrenko, Head of Product at Quantum Circuits and Neil Wu Becker, Head of Marketing for Quantum Circuits. Quantum Circuits presented at Q2B 2024 Silicon Valley at the ...
