In the present paper we describe the design of a quantum random generator based on a new concept of a single photon position sensitive device (PSD). In this scheme, the PSD should identify the position of an impinging photon between a couple of SPADs. The front end circuit is then able to process the signal and extract the random bit reducing the non-idealities introduced by the system. The device has been designed and fabricated using a 0.15 m CMOS technology and now it is under test for characterization.

Abstract
In the present paper we describe the design of a quantum random generator based on a new concept of a single photon position sensitive device (PSD). In this scheme, the PSD should identify the position of an impinging photon between a couple of SPADs. The front end circuit is then able to process the signal and extract the random bit reducing the non-idealities introduced by the system. The device has been designed and fabricated using a 0.15 m CMOS technology and now it is under test for characterization.File in questo prodotto:
