无限维两体量子系统可分态的一个必要充分条件OA北大核心CSTPCD
A Necessary and Sufficient Condition for Separable States in Infinite Dimensional Bipartite Quantum Systems
构造所考虑的量子系统与辅助量子系统张量积空间中的经典态,利用经典态在辅助复合系统的偏迹运算,研究了无限维两体复合量子系统态纠缠的识别问题,得出了无限维两体复合量子系统态可分的一个必要充分条件,推广了Li Nan和Luo Shunlong的有限维复合量子系统的相关结果.对于识别无限维量子态的纠缠或可分是一个补充.
The classical state in tensor product space of considering quantum systems and ancillary quantum systems was constructed. By taking partial trace over ancillary composite quantum systems, the problem of detecting entanglement for states in infinite dimensional bipartite composite quantum system was studied. A necessary and sufficient condition for separable states in infinite dimensional bipartite quantum systems was obtained. The above work extended t…查看全部>>
