(PhysOrg.com) -- Physicists have demonstrated a system in which light is used to control the motion of an object that is large enough to be seen with the naked eye at the level where quantum mechanics governs its behavior.

Because their quantum superfluid is simply set up by shining laser beams on the device, it can lead to practical ultrasensitive detectors.
