Distinguishability for the ququad-ququad orthogonal maximally entangled states. (arXiv:1810.04460v1 [quant-ph])
来源于:arXiv
We study the distinguishability of a particular type of maximally entangled
states -- the "ququad-ququad" states which are tensor products of Bell states
in $\mathbb{C}^4\otimes\mathbb{C}^4$. We first prove that any three orthogonal
ququad-ququad maximally entangled states can be distinguished with LOCC. Then
we use a new approach of semidefinite program to construct all sets of four
ququad-ququad orthogonal maximally entangled states that are
PPT-indistinguishable and we find some interesting sets of six states having
interesting property of distinguishability. Also, we show that our approach of
the optimization problem can make some computational complex problem more
tractable. 查看全文>>
