Researchers from the University of Vienna have used lasers to levitate and cool a glass nanoparticle into the quantum regime. Although it is restricted in a room-temperature atmosphere, the particle’s motion is completely managed by the laws of quantum physics. The researchers are thrilled about the possibilities of their work. The quantum motion of solids has also been studied by other groups all across the world, along with the researchers in Vienna.  The research opens the door for new opportunities for unique sensing performance, the study of fundamental processes of heat engines in the quantum regime, as well as the study of quantum events comprising large masses.
