Quantum Information Science

The Quantum Information Science (QIS) group applies the principles and techniques of quantum physics to real-world problems in communication, computing, and sensing. The sometimes surprising behavior of light and matter at the quantum level enables results that are simply not possible in the classical world.

Research

Quantum Information Science (QIS) is a relatively new discipline based on the idea that all information is physical. While we often treat information in abstract terms (especially in the context of computer science), it is more correct to think of information as being represented as different physical states. Thus, information must obey the laws of physics. And if the information is encoded in the quantum properties of matter or light, then it is subject to the laws of quantum physics, where nonclassical effects enable results that are not possible in the classical world. QIS draws on the talents of not only physicists, but also computer scientists, mathematicians, and engineers. The research in the QIS group is aligned along three research thrusts: sensing, communication, and computing. When applied to sensing, quantum approaches afford higher precision and faster acquisition. For communication, the quantum properties of light make it possible to exchange information with privacy and security guaranteed by the laws of physics. And in computing, quantum algorithms offer remarkable improvements in efficiency.
