Bound on local minimum-error discrimination of bipartite quantum states
Donghoon Ha, Jeong San Kim
We consider the optimal discrimination of bipartite quantum states and provide an upper bound for the maximum success probability of optimal local discrimination. We also provide a…
Locking and unlocking of quantum nonlocality without entanglement in local discrimination of quantum states
Donghoon Ha, Jeong San Kim
The phenomenon of nonlocality without entanglement(NLWE) arises in discriminating multi-party quantum separable states. Recently, it has been found that the post-measurement inform…
Complete analysis to minimum-error discrimination of mixed four qubit states with arbitrary prior probabilities
Donghoon Ha, Younghun Kwon
In this work, we provide a complete analysis to minimum-error discrimination of mixed four qubit states with arbitrary prior probabilities. For the complete anaysis, the most impor…
Annihilating and creating nonlocality without entanglement by postmeasurement information
Donghoon Ha, Jeong San Kim
Nonlocality without entanglement (NLWE) is a nonlocal quantum phenomenon that arises in separable state discrimination. We show that the availability of the postmeasurement informa…
Qubit State Discrimination using Post-measurement Information
Donghoon Ha, Jeong San Kim, Younghun Kwon
We consider the optimal discrimination of nonorthogonal qubit states with post-measurement information and provide an analytic structure of the optimal measurements. We also show t…
Quantum nonlocality without entanglement depending on nonzero prior probabilities in optimal unambiguous discrimination
Donghoon Ha, Jeong San Kim
Nonlocality without entanglement(NLWE) is a nonlocal phenomenon that occurs in quantum state discrimination of multipartite separable states. In the discrimination of orthogonal se…
