Verifying energy-time entanglement via nonlocal dispersion cancellation
The authors experimentally demonstrate direct verification of continuous-variable energy-time entanglement via nonlocal dispersion cancellation under realistic telecom conditions, effectively emulating photon propagation through a 379-km optical fiber. They observe a significant violation of the separability criterion by 32 standard deviations, confirming robust entanglement suitable for secure long-distance quantum communication.
