摘要

对单光子波包与腔-量子点模型相互作用的动力学过程进行了数学推导,并通过数值模拟实现了 静态量子比特与飞行光子比特之间的相互转换。结果表明:由腔-量子点系统输出到光纤的光子是一个 平滑的波包;通过改变激光脉冲作用时间等系统参数,可实现量子点中的原子和光子的纠缠,在此基础上, 即可实现不同量子点中原子的纠缠。研究结果对解决利用腔-量子点系统来构造量子计算机的接口、 制备纠缠态以及实现受控量子门等热点问题具有积极意义。

Abstract

A mathematical derivation was carried out about dynamics of the interaction between single photon and cavity-quantum dot system model and the mutual conversion was realized between the stationary qubit and flying qubit by numerical stimulation. The results show that the photon emitted from the cavity-quantum dot system is a smooth wave packet. By changing the parameters such as laser pulse time, the entanglement between photon and atom in quantum dot can be realized, which is the basis for realizing the entanglement between atoms in different quantum dots. These results are important to solve such hot problems as the construction of interface of quantum computers based on cavity-quantum dot system, preparation of entangled states and realization of controlled gates in the system.
