We are an interdisciplinary team combining expertise in different fields such as quantum information, quantum and classical cryptography, mathematics and quantum optics. Examples of our research interests include quantum random number generators, quantum key distribution but also any other cryptographic tasks with a quantum advantage. One particular focus of ours is to introduce methods for certifying the quantum behaviour of devices; this is closely related to the device-independent approach to quantum information. Our team works closely with the optics and engineering teams for the real-world implementation and deployment of our products.
