The second term ˜ ρA1∪A2 breaks the invariance under partial transposition, but its matrix elements are of order 2 −d/2

Separable form of the reduced density matrix In the previous section, we have established that the reduced density matrix ρA1∪A2 takes the form ρA1∪A2 = ρs A1∪A2 + ˜ρA1∪A2 , (65) w
