摘要
提出了一种利用Ξ—型原子与处于SU (1,1)相干态的腔场的相互作用实现类自旋腔场Greenberger -Horne -Zeilinger(GHZ)态的新方案 ,并通过对腔场宇称的测量 ,否定了局域隐变量理论 ,该方案不需要违背Bell不等式 ,同时 ,指出了该方案的适用范围。
A new scheme is presented for generating a spin-type cavity field entangled state via Ξ-type atom-SU(1,1) coherent state cavity field interaction, and the local hidden variable theory is vetoed by mearing the cavity-field parity. The scheme does not violate Bell's inequality. In the end, the possible range of application is indicated in the future.
