Transferring Three-Dimensional Quantum States and Implementing a Quantum Phase Gate Based on Resonant Interaction between Distant Atoms

We propose a more efficient and reliable scheme for transferring quantum states between distant atoms than previous schemes based on resonant atom-cavity interaction. In addition, our system can also be used to implement a controlled phase gate with high fidelity.
