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…

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…

Fault-tolerant Preparation of Distant Logical Bell Pair -- with application in the magic square game
Andy Zeyi Liu, Debbie Leung
Measures of quantum nonlocality traditionally assume perfect local computation. In real experiments, however, each computational primitive is imperfect. Fault-tolerant techniques e…
