Quantum randomness on laser written glass integrated circuit

Quantum random number generators are devices capable of taking advantage of the inherently present randomness in some quantum systems to generate random numbers. Such random numbers are not only non-deterministic, but they can be made unpredictable by an attacker. Due to these properties, quantum random number generators are critical components in various fields such as cryptography and scientific simulations. Photonic integrated circuits allow to reduce the implementation complexity and power consumption of this type of optical systems, while guaranteeing a higher stability. A novel type of integrated circuits is obtained on glass through femtosecond laser micromachining technology. This experimental thesis focuses on the implementation of a custom-designed glass photonic integrated circuit to realize a heterodyne-based continuous variable quantum random number generator.
