文摘
Generalizing the two-qubit purification method of Bennett et al. (Phys. Rev. Lett. 76, 722-25 1996), we present a three-qubit protocol, to purify partially entangled pairs of generalized Werner states, with application of controlled-not gates, projective measurements and Pauli rotations. The protocol is simple and recyclable and the fidelity of the purified states converge rapidly to 1, after a few cycles.
