Our device uses a prepare-and-measure protocol where two states are prepared, a coherent state or the vacuum, and then a detector performs unambiguous state exclusion to discriminate between them. The protocol is semi-device independent, while the randomness is certified only with an assumption on the overlap of the two prepared states. The QRNG is also self-testing, meaning that we can monitor the correct function of the setup in real-time. This implementation is a prototype, implemented in a box using off-the-shelf commercial components. With our simple setup we achieved real-time extraction of truly random numbers with a rate of 6.8 MHz.</i></p> Dewey 500.2 35 Groupe de physique appliquée 135 false 1408 Groupe Zbinden e5090d6d-716f-41eb-ae6d-ae8db182861a Master thesis Public masters_thesis_with_corrections.pdf 22953030 application/pdf e9ca5065dddc88c0da673763b9dfaf98ed18f54e62221ebfc5dad33eb3f1a9a4 openAccess Faculté des sciences / Section de physique / Groupe de physique appliquée
