基于半导体共振腔的量子位与量子网络构建

以半导体共振腔内光子与原子的纠缠特性作为量子位，通过半导体共振腔电动力学系统将原子态转换成光子态， 根据半导体共振腔的工作特性，提出共振腔内原子与光子弱耦合与强耦合的判断条件， 并利用外加电磁场对原子的量子态进行操控，从而完成量子逻辑门的操作，再通过各共振腔量子电动力学(CQED)系统间的纠缠进行量子位扩充，实现量子计算与量子网络。介绍微碟型共振腔与单一量子点等多种模型，有助于将量子运算与量子通讯的概念转变为半导体量子器件的研制。

Construction of qubits and quantum networks based on Semiconductor cavity

The entanglement properties of photon and atom within semiconductor resonance cavity were chosen as qubits, atom state was transformed to photon state through electrodynamics system of semiconductor resonance cavity, according to the operation characteristics of semiconductor resonance cavity, judgment conditions of weak and strong coupling of atom and photon in semiconductor resonance judgment were proposed, also the quantum state of atom was manipulated by utilizing external electromagnetic field, the operation of quantum logical gate was thereby completed, then the qubits were expanded though the entanglement among each cavity quantum electrodynamics (CQED) system, realized the quantum computing and networking. Introduced various models such like micro disc resonance cavity, single quantum dot, so forth, which would benefit turning the conception of quantum computing and communicating into the development and manufacturing of semiconductor quantum devices.
