Abstract

Secure and true random numbers are a fundamental element in different applications in science, statistics and cryptography. In some critical cases, such as security protocols and cryptography, the numbers are required to be secure and known only by the legitimate user; at the same time, they must be provided at a fast rate. The thesis has the objective of realizing a fast and stable quantum random number generator for the continuous streaming of numbers. The measurement of the quadrature of the electromagnetic vacuum enables us to obtain a high generation rate with a simple implementation. The stability over time is guaranteed by the simplicity of the experimental realization and the homodyne measurement. The possibility of a continuous generation let us implement an online public provider of random sequences.

Secure and true random numbers are a fundamental element in different applications in science, statistics and cryptography. In some critical cases, such as security protocols and cryptography, the numbers are required to be secure and known only by the legitimate user; at the same time, they must be provided at a fast rate. The thesis has the objective of realizing a fast and stable quantum random number generator for the continuous streaming of numbers. The measurement of the quadrature of the electromagnetic vacuum enables us to obtain a high generation rate with a simple implementation. The stability over time is guaranteed by the simplicity of the experimental realization and the homodyne measurement. The possibility of a continuous generation let us implement an online public provider of random sequences.
