4 p, 341.0 KB Bounds on entanglement assisted source-channel coding via the lovász number and its variants / Cubitt, Toby (University of Cambridge) ; Mančinska, Laura (National University of Singapore) ; Roberson, David (Nanyang Technological University) ; Severini, Simone (University College London) ; Stahlke, Dan (Carnegie Mellon University) ; Winter, Andreas (Universitat Autònoma de Barcelona. Departament de Física)
We study zero-error entanglement assisted source-channel coding (communication in the presence of side information). Adapting a technique of Beigi, we show that such coding requires existence of a set of vectors satisfying orthogonality conditions related to suitably defined graphs G and H. [...]

15 p, 473.5 KB Strong converse for the quantum capacity of the erasure channel for almost all codes / Wilde, Mark M. (Louisiana State University. Department of Physics and Astronomy) ; Winter, Andreas (Universitat Autònoma de Barcelona. Departament de Física)
A strong converse theorem for channel capacity establishes that the error probability in any communication scheme for a given channel necessarily tends to one if the rate of communication exceeds the channel's capacity. [...]

11 p, 443.2 KB Quantum learning of classical stochastic processes : The completely-positive realization problem / Monras Blasi, Àlex (Universitat Autònoma de Barcelona. Departament de Física) ; Winter, Andreas (Universitat Autònoma de Barcelona. Departament de Física)
Among several tasks in Machine Learning, is the problem of inferring the latent variables of a system and their causal relations with the observed behavior. A paradigmatic instance of such problem is the task of inferring the Hidden Markov Model underlying a given stochastic process. [...]
