About Us

We are an internationally regarded quantum computing research group in the Faculty of Computing at the University of Latvia. Our group is currently led by Andris Ambainis, and we focus on the theoretical aspects of quantum information including quantum algorithms, computational complexity, communications, and cryptography.
