Quantum hacker’s suitcase. Optical part of the eavesdropping setup


The suitcase contains Eve’s copy of Bob’s photon detection unit and a faked-state generator. The latter consists of many components mounted on an optical breadboard: 9 semiconductor lasers (roughly 800 nm wavelength, fiber-coupled), polarization controllers, variable attenuators, 2x2 fused fiber couplers. On the lid, control electronics for the faked-state generator is mounted.

This picture from Quantum hacking lab gallery is included in Picture Collection (ref. nr. a290-32) on Photo Pages.
