Physicists create time crystals: New form of matter may hold key to developing quantum machines
Observation of discrete time-crystalline order in a disordered dipolar many-body system. Nitrogen–vacancy centres (blue spheres) in a nanobeam fabricated from black diamond are illuminated by a focused green laser beam and irradiated by a microwave source. Credit: (c) Nature (2017). DOI: 10.1038/nature21426 Harvard physicists have created a new form of matter - dubbed a time crystal - which could offer important insights into the mysterious behavior of quantum systems.
