基于推广的Beell态测量d-能级系统的可编程量子处理器(英文)

Programmable Quantum Processor for d-Level Systems Based on Generalized Bell States Measurement

将普适可编程量子处理器推广到了d 能级的量子系统情况 ,并给出了一个实现普适量子门阵列的具体方案 .文中的普适量子门阵列由一个Bell测量和 3个推广的控制非门组成 .为了完成d 能级系统的Bell测量和控制非门操作 ,现引入推广的Bell基和推广的控制非门操作 ,并讨论了这些Bell基及控制非门的性质 .

Generalized universal programmable quantum processor to the d-level quant um system and a explicit scheme to implement a universal gate array is given. Th i s universal gate array consists of a joint Bell measurement and three controlled -NOT gates. In order to complete the Bell measurement and the controlled-NOT o peration for the d-level quantum system, we have introduced the generalized Bel l bases and generalized controlled-NOT operation for qudits, and discussed the properties of the generalized Bell basis states and controlled-NOT gate.
