量子信息的物理实现及发展概况

The Physics Realization and the Development General Situation of Quantum Information

文章指出了量子信息处理的物理实现方案有:离子阱(Ion trap),腔量子电动力学(腔QED),核磁共振(NMR),量子点(Quantum dot),基于Josephson结的超导系统等。着重介绍了最有前景的腔QED方案,同时介绍了量子信息的发展概况,并指出目前亟待解决的问题。

The article pointed out that carries out the schemes of physics in the quantum information processing to have： the Ion trap（Ion trap）, the cavity quantum electrodynamics（ Cavity QED） , the nuclear magnetic resonance（ NMR）, the quantum dot（Quantum dot）, according to superconductive system of the Josephson knot etc.. Emphasized to introduce to have most the scheme of cavity QED of the foreground, introduced the development general situation of the quantum information at the same time, and point out that the urgently needs the problem for resolve currently.
