Abstract
We propose a scheme to implement a twobit conditional quantum phase gate and generate a multiatom cluster state and a twoatom threedimensional entangled state based on photon emission and absorption processes In the scheme a Λtype atom and a Vtype atom are individually trapped in two spatially separated cavities connected by an optical fiber By choosing the interaction time and the ratio of coupling parameters appropriately the gate operation and entanglement generation can be determinately achieved We also discuss the influence of photon Leakage on the fidelities of the gate and entanglement and show that the scheme is scalable and feasible in the experimental realization and further utilization
