压缩光场的纠缠准概率

Entanglement quasiprobabilities of squeezed light

J. Sperling, W. Vogel

摘要:

我们证明了利用准概率的负性完全刻画纠缠的可行性。这需要一个复杂的数学问题的完整解决方案,所谓的可分性特征值问题。对于非高斯连续变量量子态,即经历退相的双模压缩态,我们得到了它的解。这是量子相关辐射场实验的标准场景。

英文摘要:

We demonstrate the feasibility to completely characterize entanglement by negativities of quasiprobabilities. This requires the complete solution of a sophisticated mathematical problem, the so-called separability eigenvalue problem. Its solution is obtained for a non-Gaussian continuous variable quantum state, a two-mode squeezed state undergoing dephasing. This is a standard scenario for experiments with quantum-correlated radiation fields.
