Enhanced Optimal Quantum Communication by Generalized Phase Shift Keying Coherent Signal
Min Namkung, Jeong San Kim
It is well known that the maximal success probability of the binary quantum communication can be improved by using a sub-Poissonian non-standard coherent state as an information ca…
Indirect Measurement for Optimal Quantum Communication Enhanced by Binary Non-standard Coherent States
Min Namkung, Jeong San Kim
It is well known that the Helstrom bound can be improved by generalizing the form of a coherent state. Thus, designing a quantum measurement achieving the improved Helstrom bound i…
Violation of general Bell inequalities by a pure bipartite quantum state
Elena R. Loubenets, Min Namkung
In the present article, based on the formalism introduced in [Loubenets, J. Math. Phys. 53, 022201 (2012)], we derive for a pure bipartite quantum state a new upper bound on its ma…
Two-sequential Conclusive Discrimination between Binary Coherent States via Indirect Measurements
Min Namkung, Elena R. Loubenets
A general scenario for an -sequential conclusive state discrimination introduced recently in Loubenets and Namkung [arXiv:2102.04747] can provide a multipartite quantum communic…
Conclusive discrimination by sequential receivers between arbitrary quantum states
Elena R. Loubenets, Min Namkung
In the present article, we develop a general framework for the description of discrimination between quantum states by sequential receivers in the case where each…
