World-first: Quantum ground state of rotation achieved in silica nanorotor
SMRTR summary
European researchers achieved the first-ever quantum ground state cooling of a silica nanorotor in two dimensions, using intense laser light to trap the particle and cool its rotational motion to near absolute zero through coherent scattering. This breakthrough enables quantum torque sensing and rotational matter interferometry applications for next-generation quantum technologies.
