image: In the center is an image showing the mechanical oscillator which was cooled to its ground state and then successfully excited by a single quanta of energy. Depicted above is the simulation of the shape of the mechanical mode that is used in the experiment. The bottom picture shows an artist's impression of a quasi-probabilistic distribution of the quantum state. This material relates to a paper that appeared in the Sept. 21, 2017, online issue of Science, published by AAAS. The paper, by S. Hong at University of Vienna in Vienna, Austria, and colleagues was titled, "Hanbury Brown and Twiss interferometry of single phonons from an optomechanical resonator." view more
