Photon-Number Splitting (PNS) Attacks in Weak Coherent Pulse QKD: Simulation and Countermeasures

2026 · EPJ Web of Conferences

For a start, Quantum Key Distribution offers security not depending on any fundamental assumption. However, actual realizations choose to use weak coherent pulses as photon sources, rather than the ideal single-photon state, which bears security …
