Li-Schematic (IMAGE) Purdue University Caption IMAGE CAPTION: This is a schematic of an optical tweezer used in a vacuum chamber by Purdue University researchers, who controlled the "electron spin" of a levitated nanodiamond. The advance could find applications in quantum information processing, sensors and studies into the fundamental physics of quantum mechanics.
