Due to limited space, registration for in-person participation (which is separate from the hybrid town hall) is by invitation only. Please do not register here unless you have received an emailed invitation. There is no registration fee. In-person attendance is important to ensure completeness of working group discussions leading to the report on quantum sensing strategy. Please indicate which days you will be able to attend in-person. The presentation component will be a hybrid town hall on the afternoon of 4/27 in which people may give short, 2-slide presentations on new ideas or recent progress that has yet not been presented in recent community studies such as Snowmass. If you wish to to also make a short presentation in the town hall, please also submit an abstract in the 'call for abstracts' section.
