Multipartite unlockable bound entanglement in the stabilizer formalism
Guoming Wang, Mingsheng Ying
We find an interesting relationship between multipartite bound entangled states and the stabilizer formalism. We prove that if a set of commuting operators from the generalized Pau…
Discrimination between pure states and mixed states
Chi Zhang, Guoming Wang, Mingsheng Ying
In this paper, we discuss the problem of determining whether a quantum system is in a pure state, or in a mixed state. We apply two strategies to settle this problem: the unambiguo…
Realization of positive-operator-valued measures by projective measurements without introducing ancillary dimensions
Guoming Wang, Mingsheng Ying
We propose a scheme that can realize a class of positive-operator-valued measures (POVMs) by performing a sequence of projective measurements on the original system, in the sense t…
Unambiguous discrimination among quantum operations
Guoming Wang, Mingsheng Ying
We address the problem of unambiguous discrimination among a given set of quantum operations. The necessary and sufficient condition for them to be unambiguously distinguishable is…
