Genuinely nonlocal product bases: Classification and entanglement-assisted discrimination

S Rout, AG Maity, A Mukherjee, S Halder, M Banik - Physical Review A, 2019 - APS
An orthogonal product basis of a composite Hilbert space is genuinely nonlocal if the basis
states are locally indistinguishable across every bipartition. From an operational point of …

LOCC distinguishability of unilaterally transformable quantum states

S Bandyopadhyay, S Ghosh, G Kar - New Journal of Physics, 2011 - iopscience.iop.org
We consider the question of perfect local distinguishability of mutually orthogonal bipartite
quantum states, with the property that every state can be specified by a unitary operator …

Several nonlocal sets of multipartite pure orthogonal product states

S Halder - Physical Review A, 2018 - APS
It is known that there exist sets of pure orthogonal product states which cannot be perfectly
distinguished by local operations and classical communication (LOCC). Such sets are …

Distinguishability of quantum states by separable operations

R Duan, Y Feng, Y Xin, M Ying - IEEE Transactions on …, 2009 - ieeexplore.ieee.org
In this paper, we study the distinguishability of multipartite quantum states by separable
operations. We first present a necessary and sufficient condition for a finite set of orthogonal …

Three maximally entangled states can require two-way local operations and classical communication for local discrimination

M Nathanson - Physical Review A—Atomic, Molecular, and Optical …, 2013 - APS
We show that there exist sets of three mutually orthogonal d-dimensional maximally
entangled states which cannot be perfectly distinguished using one-way local operations …

Limitations on separable measurements by convex optimization

S Bandyopadhyay, A Cosentino… - IEEE Transactions …, 2015 - ieeexplore.ieee.org
We prove limitations on LOCC and separable measurements in bipartite state discrimination
problems using techniques from convex optimization. Specific results that we prove include …

More nonlocality with less purity

S Bandyopadhyay - Physical Review Letters, 2011 - APS
Quantum information is nonlocal in the sense that local measurements on a composite
quantum system, prepared in one of many mutually orthogonal states, may not reveal in …

Locally indistinguishable subspaces spanned by three-qubit unextendible product bases

R Duan, Y Xin, M Ying - Physical Review A—Atomic, Molecular, and Optical …, 2010 - APS
We study the local distinguishability of general multiqubit states and show that local
projective measurements and classical communication are as powerful as the most general …

LOCC indistinguishable orthogonal product quantum states

X Zhang, X Tan, J Weng, Y Li - Scientific reports, 2016 - nature.com
We construct two families of orthogonal product quantum states that cannot be exactly
distinguished by local operation and classical communication (LOCC) in the quantum …

Distinguishability classes, resource sharing, and bound entanglement distribution

S Halder, R Sengupta - Physical Review A, 2020 - APS
Suppose a set of m-partite, m≥ 3, pure orthogonal fully separable states is given. We
consider the task of distinguishing these states perfectly by local operations and classical …
