The CQC research group's contributions to the theory of quantum computation and quantum cryptography include pioneering work on the relationship between physics and computation and the qualitative distinction between classical and quantum computing, the invention of entanglement-based cryptography, and collaborative work on the first demonstration of a quantum algorithm that outperforms all classical algorithms and on the development of quantum privacy amplification techniques which (it is now understood) allow efficient quantum cryptography over arbitrarily long distances.

Group members are currently working on the foundations of quantum information science and of quantum physics, the design and analysis of quantum computing algorithms and of cryptographic protocols whose security is guaranteed by quantum theory and/or the impossibility of signalling faster than light, the theories of entanglement and nonlocality, and the practical problems of building workable quantum computers and secure quantum cryptosystems. We are also exploring applications of quantum information processing to imaging, metrology, and other tasks.
