Entangling Distant Qubits via Flying Photons Under Thermal Noise Protected by Multi-Time-Bin Encoding
Entangling distant stationary qubits—such as superconducting qubits, color centers, trapped ions, and phononic modes—commonly relies on flying photons transmitted through noisy channels. The fidelity of remote entanglement is severely degraded by channel noise. While entanglement purification can theoretically mitiga...
