are input ports and each port is supplied with an arbitrary single-photon state, while are the corresponding outputs, respectively. θ and 2θ represent phase shifts in the coherent probe beam induced by Kerr interaction between photons. is a phase shift gate. Each represents a phase shift on the signal photons based on classical feed-forward information.
