Informal discussion group covering the application of quantum computing to quantum chemistry. We meet fortnightly for lunch - pizza is provided! Contributors come from various backgrounds, and we are open to suggestions for future discussion topics.

Ask to join the mailing list to be notified about upcoming meetings. Anyone is free to attend!
