摘要
We propose a simple linear optical scheme for directly implementing an ancilla-free two-qubit quantum SWAP gate with high success probability. The proposed setup consists of only simple linear optical elements and photon detectors without introducing additionally ancillary single photons or entangled photons sources. The scheme is feasible and within the reach of current experimental technology.
