Completely positive semidefinite rank
An n× n matrix X is called completely positive semidefinite (cpsd) if there exist d× d Hermitian positive semidefinite matrices {Pi}i=1n (for some d≥ 1) such that Xij= Tr (PiPj) , for all i, j∈ { 1 , … , n}. The cpsd-rank of a cpsd matrix is the smallest d≥ 1 for which such a representation is possi...
