Implementation of SWAP test for two unknown states in photons via cross-Kerr nonlinearities under decoherence effect
We present an optical scheme for a SWAP test (controlled swap operation) that can determine whether the difference between two unknown states (photons) using cross-Kerr nonlinearities (XKNLs). The SWAP test, based on quantum fingerprinting, has been widely applied to various quantum information proc...
