  4. We demonstrate the feasibility of entanglement swapping after storage by performing Bell-state measurements on polarization qubits stored in two independent room-temperature quantum memories, a crucial step in developing a quantum repeater.

  5. We report on progress towards achieving entanglement swapping between independent cavity-enhanced entanglement sources that are tuned for quantum memory operation. Together with quantum memories, we envision the demonstration of a Type II quantum repeater.

  6. We simulate entanglement sharing between two end-nodes of a linear chain quantum network using SeQUeNCe, an open-source simulation package for quantum networks. Our focus is on the rate of entanglement generation between the end-nodes with many repeaters with a finite quantum memory lifetime. Numerical and analytical simulations show limits of connection performance for a given number of repeaters involved, memory lifetimes, the distance between the end-nodes, and an entanglement management protocol. Our findings demonstrate that the performance of quantum connection depends highly on the entanglement management protocol, which schedules entanglement generation and swapping, resulting in the final end-to-end entanglement.
