Abstract

我们建议二个计划在旋转链生产长途的纠纷。第一基于一个可控制的相互作用系统，一个人从一个纠缠的内核开始并且增加一步一步地削弱相互作用旋转到边界地点，然后，纠纷将越来越长被扩大，它的值等于它的内核的。，第二与为边界 qubits 是不在的体积磁场(B) 基于一个一致相互作用(J) 系统 B/J > 5，一个人能获得近完美的长距离纠纷。极端低的温度在两个计划被需要。

Generation of Long-Distance Entanglement in Spin System

Xi Xiao-Qiang, Liu Wu-Ming

We propose two schemes to produce long-distance entanglement in a spin chain. The first is based on a controllable interaction system, one starts from an entangled kernel and adds weaken interaction spins to the boundary sites step by step, then the entanglement will be extended longer and longer and its value is equal to that of its kernel. The second is based on a uniform interaction (J) system with a bulk magnetic field (B) that is absent for the boundary qubits, as long as B|J > 5, one can obtain near perfect long distance entanglement. Ultra-low temperature is needed in both schemes.
