Sanz, Mikel ; Pérez García, David ; Cirac, Juan I. ; Wolf, Michael ; González Guillén, Carlos Eduardo | 2009We show that two different tensors defining the same translational invariant injective Projected Entangled Pair State (PEPS) in a square lattice must be the same up to a trivial gauge freedom. This allows us to characterize the existence of any [...]texto impreso
In this paper, Wielandt's inequality for classical channels is extended to quantum channels. That is, an upper bound to the number of times a channel must be applied, so that it maps any density operator to one with full rank, is found. Using th[...]texto impreso
Schuch, Norbert ; Poilblanc, Didier ; Cirac, Juan I. ; Pérez García, David | American Physical Society | 2012-09We study resonating valence bond (RVB) states in the projected entangled pair states (PEPS) formalism. Based on symmetries in the PEPS description, we establish relations between the toric code state, the orthogonal dimer state, and the SU(2) si[...]
