Samenvatting

The desire for secure communications and the advent of quantum computing has spurred innovation into key-distribution technologies that are secure against future quantum computers. Computationally secure solutions based on post quantum algorithms and physically-secure solutions using either discrete-variable or continuous-variable quantum key distribution (CV-QKD) have been proposed. The attraction with CV-QKD systems in particular is the potential to leverage the vast knowledge base and access scaling benefits of photonic integration for conventional coherent optical communication for key distribution. CV-QKD requires detailed characterization of coherent receiver hardware, specifically noise generated by electronics and shot noise caused by the local oscillator (LO) laser. This work investigates the temporal stability of the receiver noise power which defines the amount of trusted noise in the quantum link used to compute the secret key rate (SKR). Depending on the noise power’s stability, this characterization must be repeated often, typically in the order of seconds. Therefore, this work explores the possibility of using the shot noise measurement as a source of quantum random numbers, which is required by a CV-QKD transceiver. This work enables further integration of the CV-QKD hardware, removing the need for a separate quantum random number generator (QRNG).
