Ultracold Quantum Sensing 2023

Quantum sensing with ultracold atoms has led to clocks and atom interferometers with astonishing performance. The best clocks would go wrong by only one second over the lifetime of the universe, a precision of 10^-18, and commercial ultracold atom clocks reach 10^-16. These clocks have important applications in science and society: the search for changing fundamental constants, the synchronization of radio telescopes or telecommunication networks, navigation and much more. Similarly atom interferometers have applications in the detection of underground structures, inertial navigation, and fundamental science, such as the search for dark matter or the detection of gravitational waves in new frequency ranges.

The goal of the workshop is to enable discussions between leading ultracold quantum sensor researchers and users. The prospect of fast progress on ultracold quantum sensors, the opportunities for science, industry and society, and the large influx of financial support for this research area make it necessary to accelerate discussions between ultracold quantum sensing stakeholders, otherwise large amounts of research time and funding might be poured into misguided directions. Ideally discussions will accelerate progress by avoiding research groups to get stuck on problems others solved already, will guide sensor development into directions that actually matter to users, identify new applications for sensors, and help to push the frontiers of sensors with novel ideas.

The workshop focuses on four complementary topics:

• Optical clocks
• Atom interferometry and continuous atomic sources
• Science with ultracold quantum sensors
• Industry ultracold quantum sensors and their applications
