Communication and Error Correction via Polarisation of Single Photons and Time Ordering

Abstract: This research study aims to investigate the capacity of single photons to carry information through polarization and time ordering and proposes a protocol called Beyond Pulse Position Modulation (BPPM) to improve photon-based communication reliability over longer distances with limited power. Such a protocol may be used in any communication scenario where energy efficiency is important, e.g., in satellite communication or where pulse position modulation (PPM) typically is used. The study compares various metrics such as information bits per symbol, photon, and time bin to evaluate the system’s efficiency and conducts a comparative analysis of BPPM, Pulse Position Modulation (PPM), On-Off Keying (OOK), andGeneral protocol’s effectiveness. (The simulations were conducted using the Python programming language with Visual Studio Code IDE.)
