What new computation, communication, and cryptography capabilities are enabled by use of quantum physics? We have shown that absolutely secure digital signatures can be created using quantum states; stored programs can also be encoded in quantum states, such that they can only be executed once (quantum states collapse after measurement). Currently, we are working on control techniques for quantum systems, and new quantum algorithms based on symmetry transforms.
Quantum Information is studied by many people and research groups. MIT offers several weekly research seminars, a QIS Seminar mailing list, courses (both graduate and undergraduate) and an e-print and journal search interface to keep abreast of current research.
In 1994, CSAIL member Peter Shor showed that quantum computers, if built, would be able to break most of the cryptographic codes used in modern electronic commerce. This result played a central role in launching quantum computing and information as a field of study. Today Shor works on a variety of topics in quantum information theory and quantum algorithms. Scott Aaronson's research focuses on the limits of quantum computers, and more generally, on the interface between computational complexity theory and physics.
