Exponentially many entanglement and correlation constraints for multipartite quantum states

Eltschka, Christopher ; Huber, Felix ; Gühne, Otfried ; Siewert, Jens


We present a family of correlation constraints that apply to all multipartite quantum systems of finite dimension. The size of this family is exponential in the number of subsystems. We obtain these relations by defining and investigating the generalized state inversion map. This map provides a systematic way to obtain local unitary invariants of degree two in the state and is directly linked to ...
