Despite doubling down onits … WebThe photon number splitting attack (PNS) is an individual attack. It is applied on realistic photon sources emitting weak coherent pulses which generate single photons only with a certain probability. With a small probability, multi-photon pulses are emitted containing two or more photons having the same polarization.
