Quantum spins reportedly nudge a levitated, centimeter-scale graphite plate

SciNatureNews says OIST researchers levitated a roughly 128 mg graphite plate with a nitrogen-vacancy diamond, then nudged it about 100 nanometers using laser-controlled electron spins. It calls this the first clear quantum force acting on an object large enough for gravity to matter and says the plate was eight to nine orders of magnitude more massive than objects in previous experiments.
