Time-bin entanglement at telecom wavelengths from a hybrid photonic integrated circuit

1 min read

This paper demonstrates telecom-wavelength time-bin entanglement from a hybrid photonic integrated circuit, showing that integrated time-bin hardware can reach network-relevant entanglement quality rather than remaining a purely bulk-optics encoding.

Key Results

  • Demonstrates telecom-wavelength time-bin entangled photon pairs from a hybrid photonic integrated circuit
  • Reports Bell-state fidelity of
  • Reports concurrence of
  • Strengthens the case for compact, fiber-pigtailed, mass-deployable time-bin networking hardware
