Eavesdropping experiment in Prof. Kuliks lab at the Moscow State University
Left to right: Ilia Koshkin, Ekaterina Moreva.
The experiment done by Vadim Makarov tested saturation behavior of a single photon detector based on a passively quenched silicon avalanche photodiode.
As the experiment showed, this saturation behavior of the single photon detector can be used to stage a successful attack on a quantum cryptosystem that uses two or more such detectors.
I also have the same picture without people.
