How big can something be and still be quantum? FQxI member Markus Aspelmeyer and colleagues have demonstrated optical measurement and feedback cooling of a 6-microgram superconducting sphere levitated in a magnetic trap. Read the new paper: journals.aps.org/prapplied/abst… @iqoqivienna

Optical interferometric readout of a magnetically levitated superconducting microsphere
We probe the motion of a 6-$\text{\ensuremath{\mu}}\mathrm{g}$ magnetically levitated superconducting microsphere using optical interferometry at $3\phantom{\rule{0.1em}{0ex}}\mathrm{K}$, achieving a...
