- Abstract summary: We describe a scheme for in-situ generation of multimode photon-memory entanglement within one optical cavity.
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.

- 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.
