We give a test that can distinguish efficiently between product states of n quantum systems and states which are far from product. If applied to a state psi whose maximum overlap with a product state ...
Matrix Product States: Symmetries and Two-Body Hamiltonians
Matrix Product States Symmetries Two-Body Hamiltonians
2010/4/13
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 group of a given state...
