Feedback cooling a levitated nanoparticle's libration to below 100 phonons
Jialiang Gao, Fons van der Laan, Joanna A. Zielinska +3
Macroscopic rotors are interesting model systems to test quantum theory and for quantum sensing. A promising approach for bringing these systems to the quantum regime is to combine…
