Resource distillation in convex Gaussian resource theories
Hyejung H. Jee, Carlo Sparaciari, Mario Berta
It is known that distillation in continuous variable resource theories is impossible when restricted to Gaussian states and operations. To overcome this limitation, we enlarge the…
Practical randomness amplification and privatisation with implementations on quantum computers
Cameron Foreman, Sherilyn Wright, Alec Edgington +2
We present an end-to-end and practical randomness amplification and privatisation protocol based on Bell tests. This allows the building of device-independent random number generat…
Quasi-polynomial time algorithms for free quantum games in bounded dimension
Hyejung H. Jee, Carlo Sparaciari, Omar Fawzi +1
We give a converging semidefinite programming hierarchy of outer approximations for the set of quantum correlations of fixed dimension and derive analytical bounds on the convergen…
Non-additivity in classical-quantum wiretap channels
Arkin Tikku, Mario Berta, Joseph M. Renes
Due to Csiszar and Koerner, the private capacity of classical wiretap channels has a single-letter characterization in terms of the private information. For quantum wiretap channel…
