Quantum Information Science at the University of Vigo

Research interests

We are interested in those theoretical aspects of Quantum Information Science that could improve the current level of information security in computing and communication systems. We think that there are other fields related to information security, apart from cryptography, that can benefit from the use of quantum resources.
