Reaching this regime in room-temperature environments requires a stringent condition on the mechanical quality factor Q m and frequency f m , Q m f m ≳ k B T bath / h , which so far has been marginally satisfied only in a small number of systems. Here we propose and analyze a new class of systems that should enable one to obtain unprecedented Q -frequency products. The technique is based on the use of optical forces to ‘trap’ and stiffen the motion of a tethered mechanical structure, thereby freeing the resulting mechanical frequencies and decoherence rates from the underlying material properties.
