Abstract

A scheme to realize the quantum controlled phase flip (CPF) between two rare-earth ions embedded in the respective cavity was analyzed. It was found that the CPF gate between ions was robust and scalable with extremely high fidelity and low error rate. It was found that quantum information could be stored in the ground-state structure for long periods of time, and was insensitive to the electric dipole-dipole interaction. A strong coupling between a single ion and a microsphere cavity modes was easily realized.
