Non-signaling assistance in prepare-and-measure scenarios with classical communication
José Nogueira, Carlos Vieira, Lucas E. A. Porto +3
Extracting the full power of non-local correlations in prepare-and-measure (PM) scenarios requires precise control over the timing and structure of the receiver's measurements. Ind…
The most discriminable quantum states in the multicopy regime
Maria Kvashchuk, Polina Chernyshova, Lucas E. A. Porto +3
This work investigates which sets of quantum states give rise to the highest achievable success probability in minimum-error state discrimination if multiple copies of the unknown…
Measurement incompatibility and quantum steering via linear programming
Lucas E. A. Porto, Sébastien Designolle, Sebastian Pokutta +1
The problem of deciding whether a set of quantum measurements is jointly measurable is known to be equivalent to determining whether a quantum assemblage is unsteerable. This probl…
Can outcome communication explain Bell nonlocality?
Carlos Vieira, Carlos de Gois, Pedro Lauand +3
A central aspect of quantum information is that correlations between spacelike separated observers sharing entangled states cannot be reproduced by local hidden variable (LHV) mode…
Can every set of incompatible measurements lead to genuine multipartite steering?
Lucas E. A. Porto, Lucas Tendick, Daniel Cavalcanti +2
Measurement incompatibility and bipartite quantum steering are known to display a strong connection: a set of measurements is incompatible if and only if it can lead to bipartite s…
