Informal discussion group focusing 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 to in person attendants!
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 and upcoming discussions can be found below.
Join the mailing list to be notified about upcoming meetings.
📽 Recordings of our previous talks can be found on our YouTube channel.
