Informal discussion group focussing on the application of Quantum Computing to Quantum Chemistry.

We meet fortnightly for lunch, mostly during term time - talks are given in a hybrid format, but pizza is provided!

Speakers come from a wide variety of backgrounds - anyone interested in or currently working in quantum information is welcome. Please let us know if you have any suggestions for future discussion topics or speakers; a list of previous discussions can be found below.
