(2,m)-threshold quantum data hiding
Donghoon Ha, Jeong San Kim
We consider multiparty quantum state discrimination and present a multiparty quantum data-hiding scheme for one classical bit to be shared among multiple parties. In the proposed s…
Sufficient conditions for additivity of the zero-error classical capacity of quantum channels
Jeonghoon Park, Jeong San Kim
The one-shot zero-error classical capacity of a quantum channel is the maximum amount of classical information that can be transmitted with zero probability of error via a single c…
Quantum data hiding with two-qubit separable states
Donghoon Ha, Jeong San Kim
We consider the discrimination of two-party quantum states and provide a quantum data-hiding scheme using two-qubit separable states. We first provide a bound on the optimal local…
Factorizability of optimal quantum sequence discrimination under maximum-confidence measurements
Donghoon Ha, Jeong San Kim
We consider the discrimination of quantum sequences under maximum-confidence measurements and show that the optimal discrimination of a quantum sequence ensemble can always be fact…
Factorizability of multi-party quantum sequence discrimination under local operations and classical communication
Donghoon Ha, Jeong San Kim
We consider multi-party quantum sequence discrimination under local operations and classical communication(LOCC), and provide conditions under which the optimal LOCC discrimination…
An Initialization-free Quantum Algorithm for General Abelian Hidden Subgroup Problem
Sekang Kwon, Jeong San Kim
Hidden Subgroup Problem(HSP) seeks to identify an unknown subgroup H of a group G for a given injective function f defined on cosets of H. Here we present an initialization-free qu…
Quantum data-hiding scheme using orthogonal separable states
Donghoon Ha, Jeong San Kim
We consider bipartite quantum state discrimination and present a quantum data-hiding scheme utilizing an orthogonal separable state ensemble. Using a bound on local minimum-error d…
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…
Nonlocal quantum state ensembles and quantum data hiding
Donghoon Ha, Jeong San Kim
We consider the discrimination of bipartite quantum states and establish a relation between nonlocal quantum state ensemble and quantum data hiding processing. Using a bound on opt…
