Scientists have created a ‘time-crystal’ a two-body system in an experiment that seems to bend the laws of physics. A ‘two-level system’ is a basic building block of a quantum computer. Time crystals could perhaps be used to build quantum devices that work at room temperature. Time crystals were long believed to be impossible because they are made from atoms in never-ending motion. The discovery shows that not only can time crystals be created, but they have potential to be turned into useful devices.
