Paper Abstract

Securing information has been a concern for more than 4,000 years, but in the times in which we are connecting every single aspect of our businesses and lives, developing secure products and infrastructures has become a global priority. Remarkably, quantum technologies bring unique possibilities for the cryptographic world. In this talk, we will describe recent efforts on the development of a highly integrated quantum entropy source, a key component to generate unpredictable cryptographic keys in any connected device. In particular, we will present the integration of two quantum entropy sources, one in Silicon Photonics and the other in Indium Phosphide. The devices are based on the accelerated phase diffusion process observed in pulsed semiconductor lasers, a macroscopic quantum effect resulting from microscopic spontaneous emission events. Both chip implementations enable Gb/s generation rates in form factors below 2mm x 5mm in indium Phosphide and 0.5mm x 1mm in Silicon Photonics. Our results show progress towards the industrialization of quantum devices using standard semiconductor production lines and processes.
