Key Highlights:

  • Demonstrates packet-based quantum-classical network operations using Quantum Wrapper Network (QWN) architecture.
  • Successfully delivered quantum payloads with time- and wavelength-multiplexed classical headers, ensuring packet switching without disturbing quantum data.
  • Achieved coincidence-to-accidental ratios (CAR) above 22 and signal visibility over 79% across two 20 km test paths.
  • Showed that classical header BER correlates with quantum payload integrity, enabling passive network performance monitoring.

This work advances the frontier of quantum-secure networking, blending flexibility, efficiency, and interoperability for next-generation photonic infrastructure.
