As an item increases in size, its localization heightens when it undergoes quantum improvement by cooling its movement to absolute zero.Researchers, led by Oriol Romero-Isart from the Institute for Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences (ÖAW) and the Department of Theoretical Physics at the University of Innsbruck, propose an experiment in which an optically levitated nanoparticle, cooled to its ground state, progresses in a non-optical (“dark”) possible developed by magnetic or electrostatic forces. “We believe that while the supreme quantum experiment will be unavoidably challenging, it must be possible as it satisfies all the essential criteria for preparing these macroscopic quantum superposition states.
