我们考虑 D 维量子系统的各种联合状态的可分离性,我们称之为“qudits”。我们得出两个主要结果:(i)作为最大混合态和最大纠缠态混合的二量子态的可分离条件; (ii) Nqudits 最大混合状态周围可分离状态邻域大小的下界和上限。
We consider the separability of various joint states ofD-dimensional quantum systems, which we call “qudits.” We derive two main results: (i) the separability condition for a two-qudit state that is a mixture of the maximally mixed state and a maximally entangled state; (ii) lower and upper bounds on the size of the neighborhood of separable states surrounding the maximally mixed state forNqudits.
