Asia-Pacific Workshop on Trapped Quantum Systems (APTQS-2019)

This workshop, as a second meeting after APTQS-2017 at Zhuhai, aims to gather together regional experts on trapped quantum systems, to discuss challenges and new directions in the field of atomic precision metrology, quantum sensing, and quantum computing. We hope this workshop provides an inspiring venue for exploring new perspectives on fundamental understanding and breakthrough technologies, involved with trapped quantum systems.
