The density matrix 1 - K PWerner = KIT-XP-| + 3 is called a Werner state. Here [P-) = 1/V2[| TAUB) - | LATB)], and so forth for the other Bell states. Show that the above density matrix can equivalently be written as PWerner = a|T-XP-| + bl, where I is a 4 x 4 identity matrix, and determine a and b. Calculate TIPwerner. Explain why, if Trp2
