Quantum levitodynamics: Harnessing quantum motion of levitated particles for fundamental and applied quantum research — •Sungkun Hong — Institute for Functional Matter and Quantum Technologies, University of Stuttgart, 70569 Stuttgart — Center for Integrated Quantum Science and Technology (IQST), University of Stuttgart, 70569 Stuttgart, Germany

Quantum levitodynamics is a thriving new field in quantum science that aims to control the quantum motion of micro- and nanoparticles levitated, for example, in optical traps. In recent years, researchers have made rapid progress in achieving quantum control of optically levitated dielectric nanoparticles. This progress opens up exciting possibilities for the development of new quantum technologies and for testing quantum physics beyond the microscopic world. In this talk, I will give a brief overview of the field and discuss my group's research activities, in particular, our efforts to develop a novel nanophotonic platform for levitodynamics with ultrastrong quantum cooperativity.
