The main research objective of the group is to understand how quantum laws can be exploited to design novel protocols for information processing and communication, with an emphasis on quantum cryptography. The research effort goes from very abstract questions, such as security proofs of cryptographic protocols, to proposals for implementations of these protocols and collaborations with experimental groups. The group activities also cover research questions in other fields, such as quantum thermodynamics, quantum foundations, quantum optics and many-body physics.
