ALL SILICON QUANTUM COMPUTING ELEMENT, ITS MANUFACTURING METHOD AND ALL SILICON QUANTUM COMPUTER USING IT

摘要

PROBLEM TO BE SOLVED: To provide an all silicon quantum computing element, its manufacturing method and an all silicon quantum computer using it capable of providing a number of qufits much more than a present NMR quantum computer without requiring detection of a single spin or extensive progress of a fine machining technique. SOLUTION: The all silicon quantum computing element is provided with a silicon terrace 6 in a28Si isotope wafer not having a nuclear spin, a bridge 3 having an atom chain of linearly grown29Si in a step 7 of the terrace 6, a cap layer of28Si to be grown, and a ferromagnetic micro magnet (a magnet) deposited in correspondence to the bridge 3.
