Absolutely entangled sets of pure states for bipartitions and multipartitions
Baichu Yu, Pooja Jayachandran, Adam Burchardt +3
A set of quantum states is said to be absolutely entangled, when at least one state in the set remains entangled for any definition of subsystems, i.e. for any choice of the global…
A neural network oracle for quantum nonlocality problems in networks
Tamás Kriváchy, Yu Cai, Daniel Cavalcanti +3
Characterizing quantum nonlocality in networks is a challenging, but important problem. Using quantum sources one can achieve distributions which are unattainable classically. A ke…
Constraints on nonlocality in networks from no-signaling and independence
Nicolas Gisin, Jean-Daniel Bancal, Yu Cai +5
Generalising the concept of Bell nonlocality to networks leads to novel forms of correlations, the characterization of which is however challenging. Here we investigate constraints…
Almost thermal operations: inhomogeneous reservoirs
Angeline Shu, Yu Cai, Stella Seah +2
The resource theory of thermal operations explains the state transformations that are possible in a very specific thermodynamic setting: there is only one thermal bath, auxiliary s…
Semi-device-independent characterization of quantum measurements under a minimum overlap assumption
Weixu Shi, Yu Cai, Jonatan Bohr Brask +2
Recently, a novel framework for semi-device-independent quantum prepare-and-measure protocols has been proposed, based on the assumption of a limited distinguishability between the…
Structure of the set of quantum correlators via semidefinite programming
Le Phuc Thinh, Antonios Varvitsiotis, Yu Cai
Quantum information leverages properties of quantum behaviors in order to perform useful tasks such as secure communication and randomness certification. Nevertheless, not much is…
