Quantum Optomechanics with Ultracoherent Soft-Clamped Resonators

Soft-clamped mechanical resonators realise quality factors Q ~ 10 9 and quantum cooperativities C q ~ 60 already in a moderate cryogenic environment (e.g. a 4.2K flow cryostat). This enables both sideband and feedback cooling to the mechanical quantum ground state.
