Abstract
- Combining parametric driving and photon-atomic memory coupling within one optical cavity, we describe a scheme for in-situ generation of multimode photon-memory entanglement. We find that precise cavity impedance matching is neither required nor optimal to achieve high-rate entanglement for quantum networks. This protocol can be realized with existing technologies based on on-chip photonic cavities integrated with a rare-earth-ion doped quantum memory. The proposed scheme shows significant advantages in entanglement generation rates compared with start-of-the-art quantum memory protocols and experiments, with predicted Ebit generation rates of tens of MHz without ideal operating conditions. Such a photon-memory entanglement system offers a versatile resource for quantum interconnect applications.<br />Comment: 5 pages, 4 figures
