Hack the Quantum @ DEFCON17 and HAR2009
Back on the road with the vintage PDC source! Again we went to Vegas to show some hardware together with the NIST guys. We showed the basics of how to fool a single photon detector into "clicking" at the request of an eavesdropper and set up a fun fair competition for the DEFCON participants to see who could achieve the highest violation of a Bell inequality by carefully aligning the measurement basis. The Golden Handles were connected to a very fiddly polarization controller. After that Ilja joined up with Vadim in the Netherlands and presented the hacking setup to yet a different audience in Hacking at Random.
Participants in the Bell competition were given signed cards with their degree of "non-classicality", i.e. how far above 2 they managed to get the Bell value S.
