Abstract：
A protocol for generation of GHZ state and implementation of controlled phase gate is proposed in this paper. With the help of cross-Kerr nonlinearity, we can obtain GHZ state of photons with the successful probability of 100 % by nondemdition measurement. Moreover, a similar method can be exploited to implement the controlled phase gate with high efficiency by adding a new device.
