Discrimination of symmetric states in operational probabilistic theory

Kenji Nakahira

A state discrimination problem in an operational probabilistic theory (OPT) is investigated in diagrammatic terms. It is well-known that, in the case of quantum theory, if a state…

Local unambiguous discrimination of symmetric ternary states

Kenji Nakahira, Kentaro Kato, Tsuyoshi Sasaki Usuda

We investigate unambiguous discrimination between given quantum states with a sequential measurement, which is restricted to local measurements and one-way classical communication.…

Optimal quantum state discrimination with confidentiality

Kenji Nakahira, Tsuyoshi Sasaki Usuda, Kentaro Kato

We investigate quantum state discrimination with confidentiality. N observers share a given quantum state belonging to a finite set of known states. The observers want to determi…
