量子计算机存储单元相干脱散的研究

Studies of Decoherence in the Memory Cell of Quantum Computer

量子计算机存储单元的相干脱散，破坏量子态中的信息，是量子计算机难以实现的主要原因之一。本文在Ｋ．Ｒｚａｚｅｗｓｋｉ的工作基础上，针对两能级原子构造的存储单元，研究了自发发射对存储单元相干脱散的影响。

One of the main difficulties of quantum computation is that decoherence destroys the information in a quantum computer memory cell. On the basis of K. Rzazewski's work,we study the effect that spontaneous emission has on the memory cell when memory cells each be taken to be two-level atoms.
