讨论了C^2×C^n量子系统的最大纠缠混合态,得到了Negativity纠缠度下的最大纠缠混合态的解析结果,并计算了该态在非满秩情形下的量子相对熵纠缠度。
The maximally entangled mixed state in the sense of negativity for C^2×C^n system is studied, and an obvious result is obtained. Moreover the relative quantum entropy of entanglement in the maximally entangled mixed state without full rank is calculated.
