Architecture of a deterministic quantum central processing unit

摘要

We present an architecture of QCPU (quantum central processing unit) which is based on the discrete quantum gate set. QCPU can be programmed to approximate any n-qubit computation in a deterministic fashion. It can be built efficiently to implement computations with any required accuracy. QCPU makes it possible to implement universal quantum computation with a fixed, general purpose hardware. (C) 2003 Elsevier Science B.V. All rights reserved. [References: 16]
