Quantum-Enhanced Classical Communications for DPMZM-based NG-PON2 Systems

arXiv:2611.09081v1 Announce Type: new Abstract: This paper presents a framework for integrating quantum detection techniques into a Dual-Parallel Mach-Zehnder Modulator (DPMZM)-based Next Generation Passive Optical Network 2 (NG-PON2) communication system. We present a system model for the DPMZM-based NG-PON2 quantum communication system and characterize its signal-to-noise ratio (SNR), demonstrating its superiority over conventional MZM-based systems. We analyze the performance of various quantum modulation techniques, including binary phase-shift keying, quadrature phase-shift keying, and M-ary quadrature amplitude modulation.
