Abstract
In this paper we define a family of hermitian operators by which to extract what we call quantumrelativephase properties of a pure or mixed multipartite quantum state and we relate these properties to known measures of entanglement namely the mtangle and the invariant S m2 of the multilocal Lorentzgroup SL2 mathbbCotimes m Our construction is based on the orthogonal complement of a positive operator valued measure on quantum phase
