We develop the probabilistic implementation of a nonlocal gate exp[i{xi}{sigma}{sub n{sub A}}{sigma}{sub n{sub B}}] and {xi} set-membership sign [0,({pi}/4)], by using a single nonmaximally entangled state. We prove that nonlocal gates can be implemented with a fidelity of >79.3% and a consumption of =}0.353 can be implemented with the probability 79.3% and a consumption of 0.969 ebits, which is the same efficiency as the distillation-based protocol, while our method saves extra classical… CONTINUE READING
