Reaching this regime in room-temperature environments requires a stringent condition on the mechanical quality factor \$Q\_m\$ and frequency \$f\_m\$, \$Q\_mf\_m\gtrsimk\_BT\_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 unprecedented \$Q\_mf\_m\$ values. The technique is based upon using optical forces to "trap" and stiffen the motion of a tethered mechanical structure, thereby freeing the resultant mechanical frequencies and decoherence rates from underlying material properties.
