A quantum version of Wielandt's inequality
M. Sanz, D. Perez-Garcia, M. M. Wolf +1
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 ma…
A canonical form for Projected Entangled Pair States and applications
D. Perez-Garcia, M. Sanz, C. E. Gonzalez-Guillen +2
We 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 ga…
Matrix Product States: Symmetries and Two-Body Hamiltonians
M. Sanz, M. M. Wolf, D. Perez-Garcia +1
We characterize the conditions under which a translationally invariant matrix product state (MPS) is invariant under local transformations. This allows us to relate the symmetry gr…
