Sequential Strong Measurements and Heat Vision
Miguel Navascues, David Perez-Garcia
We study scenarios where a finite set of non-demolition von-Neumann measurements are available. We note that, in some situations, repeated application of such measurements allows e…
Tripartite probability distributions and communication complexity
Carlos Palazuelos, David Perez-Garcia, Ignacio Villanueva
We show that every tripartite quantum correlation generated with a Schmidt state (in particular every correlation generated with the GHZ state) can be simulated with the sending of…
The inverse eigenvalue problem for quantum channels
Michael M. Wolf, David Perez-Garcia
Given a list of n complex numbers, when can it be the spectrum of a quantum channel, i.e., a completely positive trace preserving map? We provide an explicit solution for the n=4 c…
Bell inequalities from multilinear contractions
Alejo Salles, Daniel Cavalcanti, Antonio Acín +2
We provide a framework for Bell inequalities which is based on multilinear contractions. The derivation of the inequalities allows for an intuitive geometric depiction and their vi…
PEPS as ground states: degeneracy and topology
Norbert Schuch, Ignacio Cirac, David Perez-Garcia
We introduce a framework for characterizing Matrix Product States (MPS) and Projected Entangled Pair States (PEPS) in terms of symmetries. This allows us to understand how PEPS app…
