摘要:

研究了一类压缩玻色子态和费米子态的纠缠特性。我们首先研究玻色子的情况下,考虑双模压缩态。然后,我们构造费米子的版本,以表明这种状态是最大纠缠,玻色子和费米子。为了实现这些结果,我们证明了一些关系涉及压缩玻色子态。推广到费米子的情况是通过使用格拉斯曼变量。

英文摘要:

A class of squeezed boson and fermion states is studied with particular emphasis on the nature of entanglement. We first investigate the case of bosons, considering two-mode squeezed states. Then we construct the fermion version to show that such states are maximum entangled, for both bosons and fermions. To achieve these results, we demonstrate some relations involving squeezed boson states. The generalization to the case of fermions is made by using Grassmann variables.
