Science and Technology Daily (reporter Zhang Jiaxin) A few days ago, a team led by Professor Andrew Cleland of the Pritzker School of Molecular Engineering (PME) of the University of Chicago used a device called an acoustic beam splitter to "split" phonons, thereby demonstrating their quantum properties. They demonstrated that beam splitters can be used to induce a special quantum superposition state of a phonon and further generate interference between two phonons...
