Device-independent quantum key distribution with arbitrarily small nonlocality
Lewis Wooltorton, Peter Brown, Roger Colbeck
Device-independent quantum key distribution (DIQKD) allows two users to set up shared cryptographic key without the need to trust the quantum devices used. Doing so requires nonloc…
Expanding bipartite Bell inequalities for maximum multi-partite randomness
Lewis Wooltorton, Peter Brown, Roger Colbeck
Nonlocal tests on multi-partite quantum correlations form the basis of protocols that certify randomness in a device-independent (DI) way. Such correlations admit a rich structure,…
Semidefinite programming relaxations for quantum correlations
Armin Tavakoli, Alejandro Pozas-Kerstjens, Peter Brown +1
Semidefinite programs are convex optimisation problems involving a linear objective function and a domain of positive semidefinite matrices. Over the last two decades, they have be…
