Postmeasurement information and nonlocality of quantum state discrimination
Jinhyeok Heo, Donghoon Ha, Jeong San Kim
In quantum state discrimination, nonlocality arises when optimal discrimination cannot be achieved using only local operations and classical communication. It has recently been sho…

Entanglement witness and nonlocality in confidence of measurement from multipartite quantum state discrimination
Donghoon Ha, Jeong San Kim
We consider multipartite quantum state discrimination and provide a specific relation between the properties of entanglement witness and quantum nonlocality inherent in the confide…

Multi-player quantum data hiding by nonlocal quantum state ensembles
Donghoon Ha, Jeong San Kim
We provide multi-player quantum data hiding based on nonlocal quantum state ensembles arising from multi-party quantum state discrimination. Using bounds on local minimum-error dis…
