Coherent State Assisted Entanglement Generation Between Quantum Memories
Researchers developed coherent-state-assisted protocols (CTW and COW) to generate entanglement between quantum memories using optical pulses instead of single photons. These methods achieve near-deterministic entanglement generation, exceeding the 50% success rate limit of single-photon schemes, which is crucial for high-rate multi-qubit entanglement needed in quantum networks.
