- Project Jun 16, 2026 Photon-Number-Splitting Attacks on BB84
A computational quantum-cryptography project simulating the **Photon-Number-Splitting (PNS) attack** against a noisy, lossy four-state BB84 channel, quantifying the information leaked through multiphoton pulses and locating the secrecy-capacity threshold where the secret-key rate drops to zero.
