‘Quantum Nonlocality without Entanglement’ in a Pair of Qubits

Abstract

We consider unambiguous discrimination between separable bipartite states, one being pure and the other being a rank-2 mixed state. We show that the optimal success probability achieved by separable measurements is never achieved under LOCC.

Quantum nonlocality without entanglement and state discrimination measures

Shayeef Murshid, Tathagata Gupta, Vincent Russo +1 more

An ensemble of product states is said to exhibit “quantum nonlocality without entanglement” if it cannot be optimally discriminated using local operations and classical communication (LOCC). We show that this property can depend on the chosen discrimination measure. Specifically, we construct a family of ensembles, each consisting of six linearly independent, equally probable bipartite product states, for which LOCC fails to achieve optimal minimum-error discrimination but succeeds in achieving optimal unambiguous discrimination. We further extend our construction to multipartite systems and provide strong numerical evidence that a similar separation between local and global optima is present for minimum-error discrimination, but not for unambiguous discrimination.

Limitations on Separable Measurements by Convex Optimization

Somshubhro Bandyopadhyay, Alessandro Cosentino, Nathaniel Johnston +3 more

We prove limitations on LOCC and separable measurements in bipartite state discrimination problems using techniques from convex optimization. Specific results that we prove include: an exact formula for the optimal probability of correctly discriminating any set of either three or four Bell states via LOCC or separable measurements when the parties are given an ancillary partially entangled pair of qubits; an easily checkable characterization of when an unextendable product set is perfectly discriminated by separable measurements, along with the first known example of an unextendable product set that cannot be perfectly discriminated by separable measurements; and an optimal bound on the success probability for any LOCC or separable measurement for the recently proposed state discrimination problem of Yu, Duan, and Ying.

Separable measurements, LOCC unambiguous state discrimination and entanglement witnesses

Anthony Chefles

Any separable measurement with a finite number of outcomes on a finite dimensional multiparticle quantum system can, with non-zero probability, be implemented with local operations and classical communication (LOCC). I use this fact to obtain a necessary and sufficient condition for a finite set of states of a finite dimensional multiparticle quantum system to be amenable to LOCC unambiguous state discrimination. This condition is valid for states which may be be mixed, entangled or both. It is also found to have an intriguing connection with the theory of entanglement witnesses.

Unambiguous discrimination of linearly independent pure quantum states: Optimal average probability of success

Somshubhro Bandyopadhyay

We consider the problem of unambiguous (error-free) discrimination of $N$ linearly independent pure quantum states with prior probabilities, where the goal is to find a measurement that maximizes the average probability of success. We derive an upper bound on the optimal average probability of success using a result on optimal local conversion between two bipartite pure states. We prove that for any $N\ensuremath{\ge}2$ an optimal measurement in general saturates our bound. In the exceptional cases we show that the bound is tight, but not always optimal.

Unambiguous discrimination of mixed quantum states: Optimal solution and case study

Matthias Kleinmann, Hermann Kampermann, Dagmar Bruß

We present a generic study of the unambiguous discrimination between two mixed quantum states. We derive operational optimality conditions and show that the optimal measurements can be classified according to their rank. In Hilbert space dimensions less than or equal to $5$, this leads to the complete optimal solution. We demonstrate our method with a physical example, namely, the unambiguous comparison of $n$ quantum states, and find the optimal success probability.

Optimal Unambiguous Discrimination and Nonlocality without Entanglement

Donghoon Ha, Jeong San Kim

Nonlocality without entanglement(NLWE) is a nonlocal phenomenon that occurs in quantum state discrimination of multipartite separable states. Recently, it has been found that NLWE can depend on nonzero prior probabilities in minimum-error discrimination of nonorthogonal separable states. Here, we show that even in optimal unambiguous discrimination, NLWE can depend on nonzero prior probabilities. We further show that NLWE can occur regardless of nonzero prior probabilities, even if only one state can be locally discriminated without error. Our results provide new insights into classifying sets of multipartite quantum states in terms of quantum state discrimination.
