“…When only conclusive results are allowed, one possible strategy is to maximize Bob’s guessing probability. This strategy is called minimum error discrimination 1 – 5 . Meanwhile, when the quantum states of Alice are linearly independent, it is possible for Bob to develop a strategy whereby he can trust his conclusive result 6 , 7 .…”

“…Apart from studying some general features of the optimal measurement [3,4], in the beginning mainly the minimum-error discrimination of states obeying certain symmetry properties or of two mixed states was investigated, see e. g. [5][6][7][8][9][10][11][12]. The minimum-error discrimination of more than two states that are arbitrary has gained renewed interest only recently [13][14][15][16][17][18][19].…”

“…The diagonal elements of the matrix G 1 2 W can be made non-negative by appropriately fixing the phases of the |w i vectors in the following way: right-multiply W with a diagonal unitary W ′ , whose diagonal elements will be phases. From equation (15) it is seen that right-multiplying W with W ′ merely changes the phases of the ONB vectors |w i , and that they will still satisfy equation (16). We can vary the phases in W ′ so that the diagonals of G 1 2 W W ′ are non-negative.…”
