Rank-one Quantum Games
T. Cooney, M. Junge, C. Palazuelos +1
In this work we study rank-one quantum games. In particular, we focus on the study of the computability of the entangled value . We show that the value can be efficientl…
Gapless Hamiltonians for the toric code using the PEPS formalism
Carlos Fernández-González, Norbert Schuch, Michael M. Wolf +2
We study Hamiltonians which have Kitaev's toric code as a ground state, and show how to construct a Hamiltonian which shares the ground space of the toric code, but which has gaple…
Are problems in Quantum Information Theory (un)decidable?
Michael M. Wolf, Toby S. Cubitt, David Perez-Garcia
This note is intended to foster a discussion about the extent to which typical problems arising in quantum information theory are algorithmically decidable (in principle rather tha…
Entanglement and the three-dimensionality of the Bloch ball
Lluis Masanes, Markus P. Mueller, David Perez-Garcia +1
We consider a very natural generalization of quantum theory by letting the dimension of the Bloch ball be not necessarily three. We analyze bipartite state spaces where each of the…
Testing microscopic discretization
Miguel Navascues, David Perez-Garcia, Ignacio Villanueva
What can we say about the spectra of a collection of microscopic variables when only their coarse-grained sums are experimentally accessible? In this paper, using the tools and met…
