Ashley Montanaro's homepage

I am Professor of Quantum Computation in the School of Mathematics at the University of Bristol. I'm a member of the Quantum Information Theory and Theory and Algorithms research groups.

Interested in learning about quantum computing? Check out the slides and video from a talk I gave at a South West Futurists meeting. For more, you can read an overview of quantum algorithms I wrote, or the slides from a talk I gave about my work.
We're currently advertising several postdoc positions in the Bristol Quantum Information Theory group to work on the theory of quantum computing, funded by various sources including my ERC Consolidator Grant. Search for "quantum computing theory".

Research interests

"It is difficult to give an idea of the vast extent of modern mathematics. This word 'extent' is not the right one: I mean extent crowded with beautiful detail - not an extent of mere uniformity such as an objectless plain, but of a tract of beautiful country seen at first in the distance, but which will bear to be rambled through and studied in every detail of hillside and valley, stream, rock, wood and flower. But, as for everything else, so for a mathematical theory - beauty can be perceived but not explained."

— Arthur Cayley1 (1883)

My main research interests are in the theory of quantum computing. I'm interested in all areas of the subject, but particularly quantum algorithms and computational complexity, as well as quantum query and communication complexity. I'm also interested in classical algorithms and computational complexity.
