利用四粒子x-Type态在腔量子电动力学中实现任意两粒子态的量子信息分裂

摘要

We A genuinely entangled four-particle χ-Type state can be used to realize the deterministic quantum information splitting of an arbitrary two-atom state in cavity QED is demonstrated. Comparing to others protocols of QIS, our have been some advantages protocol . The scheme does not involve Bell-state measurement and is insensitive to both the cavity decay and the thermal field. It can be easily realized with present cavity QED techniques.%提出了一个利用四粒子纠缠态x-Type态在腔量子电动力学中实现任意两粒子态的量子信息分裂方案.和其他的量子信息分裂方案相比,此方案有一些优势.方案不包含Bell基测量,并且对腔衰减和热场都不敏感.在目前的腔量子电动力学技术中更易于实现.
