查询词典 decoherence

A scheme to implement a QC subjected to decoherence and governed by untunable qubit-qubit interaction is presented.

给出一个在消相干和保持量子比特间固有相互作用情况下的量子计算机的方案。

Chapter 3 is devoted to the derivation of the master equation for the system. We find that the depasing time T2Q PCis about 100 ns when the spin decoherence is only induced by the QPC, and the repeated QPC measurement will slow down the transition rate between spin states which can be interpreted in terms of quantum Zeno effect.Meanwhile, we also study the effect of QPC measurement on two-electron spin state in double quantum dot system.

推导了系统的有效哈密顿量以及主方程、计算了测量过程中电子自旋态的演化行为；随后通过计算分析，我们发现QPC测量引起的退相干时间T2Q PC约为100ns以及高频重复的QPC测量会减缓电子自旋态之间的演化、局域系统在其初态，表现出量子Zeno效应。
