PEPS as unique ground states of local Hamiltonians
David Perez-Garcia, Frank Verstraete, J. Ignacio Cirac +1
In this paper we consider projected entangled pair states (PEPS) on arbitrary lattices. We construct local parent Hamiltonians for each PEPS and isolate a condition under which the…

Unbounded violation of tripartite Bell inequalities
D. Perez-Garcia, M. M Wolf, C. Palazuelos +2
We prove that there are tripartite quantum states (constructed from random unitaries) that can lead to arbitrarily large violations of Bell inequalities for dichotomic observables.…
