摘要
对于有限维多体量子系统中的态,D-concurrence是一个重要的纠缠测度,在过去的十年中被深入探索.将D-concurrence的概念推广到k-体分划的多体量子系统,它可以度量多体量子态在k-体分划下的非经典纠缠性,并证明了纠缠测度的一些必要性质,包括在k-可分态下纠缠测度为0,在局部酉操作下不变,在局部操作和经典通信(LOCC)下不增.
Abstract
For states in finite dimensional many-body quantum system,D-concurrence is an significant entangle-ment measure that has been explored in depth over the past decade.In this paper,the concept of D-concurrence is extended to the many-body quantum system of k-partition.It can measure the non-classical entanglement of the many-body quantum state under k-partition.Some necessary properties of the entanglement measure are proved,in-cluding that the entanglement measure is zero under k-separable state,invariant under local unitary operation,and does not increase under local operations and classical communications(LOCC).
