Quantum Information and Computation
Quantum information science was born out of the idea that information processing takes place in a concrete physical setting, in particular at the smallest scales it is quantum mechanics rather than classical physics that sets the rules of how information can be stored, error protected and communicated. In fact, quantum information itself is embodied in the state of a quantum system, qualitatively different from classical information. The modern field of quantum information and computation lies at the intersection of physics, mathematics and computer science. Its aims are the eventual construction of scalable quantum computers, of a fully-blown quantum communication network, and the integration of these into the current (classical) information processing infrastructure. As theorists we are interested both in how to achieve these goals by designing more and more efficient error-tolerant schemes, as well as in the invention of possible applications, i.e. new information tasks and protocols. Besides, we are interested in the basic laws connecting classical and quantum information, and the other resources emerging in their study: quantum entanglement, magic, optical nonlinearity, etc. If you're interested in knowing more about this exciting and multi- faceted research area, or if you'd like to collaborate or work on my group, please get in touch.
