Quantum Information, Computation and Cryptography Group
We conduct theoretical research into all aspects of quantum information processing, and into the implications of the quantum theory of computation for physics itself.
We are always interested to receive applications from strong candidates for DPhil positions. Please do not get in touch directly to enquire about DPhil positions as all applications are handled CENTRALLY. For more information, please see the main university pages.

Lectures
Introduction to Quantum Information
In this series of lectures you will learn how inherently quantum phenomena, such as quantum interference and quantum entanglement, can make information processing more efficient and more secure, even in the presence of noise.
Conferences and workshops
We organise the annual SEEQA (Seeking Quantum Advantage) conference which brings together world-leading experts in Oxford to debate the challenges and opportunities in the worldwide effort to achieve general Quantum Advantage.
We organise the Quantum Computing Theory in Practice (QCTiP) 2026 conference which brings together the academic community and industry representatives to foster discussions on how to unlock the full potential of quantum computers.
Quantum Nosh
Quantum Nosh is an informal event which starts with a short talk on an exciting quantum topic just to set the scene and then we have FREE lunch in front of the seminar room. A nice assortment of sandwiches will be served along with coffee/tea and soft drinks. This is the perfect opportunity to meet and chat with other quantum teams and quantum enthusiasts in Oxford.
Please sign up [HERE] to receive notifications of upcoming Quantum Nosh events.
