Ryoshi Computer Ni Nani Ga Dekiru Ka Chishiki Zero Kara Rikai Dekiru Genri to Shikumi (Blue Backs)

[Machine Translation] It s unsuitable for simple calculations like 1+1" and even makes copying data difficult? What is quantum mechanical parallel computing," which utilizes superposition and quantum entanglement? Why does it enable high-speed computation? What does it mean that observation" is also a form of computation? What are the quantum errors" that are inevitable in machines based on quantum mechanics? In fact, our brains are also quantum computers and when a universal" model equipped with error-correction capabilities is realized, might the mystery of the mind" be unraveled!? This book provides a thorough and easy-to-understand explanation of the essence of these computers which are set to have an impact rivaling that of the Industrial Revolution" starting from the fundamentals of quantum mechanics.

「1+1」などの単純計算には不向きで、データのコピーも難しい?状態の重ね合わせと量子もつれを活用する「量子力学的並列計算」とはなにか?なぜ高速計算が可能なのか?「観測」もまた演算であるとはどういうことか?量子力学に基づく機械に不可避の「量子エラー」とは?じつは、私たちの脳も量子コンピュータであり、エラー訂正機能を備えた「万能型」が実現したとき、「心」の謎が解き明かされる!?「産業革命以来のインパクト」をもたらす計算機の本質を、量子力学の基本から懇切丁寧に解説する。
