A note on the Bloch representation of absolutely maximally entangled states

Quantum Physics 2018-01-26 v1

Abstract

The absolutely maximally entangled (AME) states play key roles in quantum information processing. We provide an explicit expression of the generalized Bloch representation of AME states for general dimension dd of individual subsystems and arbitrary number of partite nn. Based on this analytic formula, we prove that the trace of the squared support for any given weight is given by the so-called hyper-geometric function and is irrelevant with the choices of the subsystems. The optimal point for the existence of AME states is obtained.
