Entanglement sharing schemes
Zahra Khanian, Dongjin Lee, Debbie Leung +7
We ask how quantum correlations can be distributed among many subsystems. To address this, we define entanglement sharing schemes (ESS) where certain pairs of subsystems allow enta…

Extendibility of Fermionic Gaussian States
Amir-Reza Negari, Farzin Salek
We investigate -extendibility of fermionic Gaussian states, a property central to quantum correlations and approximations of separability. We show that these states are…

Efficiently Computable Limits on EPR Pair Generation in Quantum Broadcast Channels
Patrick Hayden, Debbie Leung, Hjalmar Rall +1
We investigate the generation of EPR pairs between three observers in a general causally structured setting, where communication occurs via a noisy quantum broadcast channel. The m…
