Time crystals can be used to stabilize fragile states within quantum computers, potentially giving them an edge over conventional computers one day.
When Nobel Prize winner Frank Wilczek first theorized the existence of time crystals in 2012, he said that their defining characteristic is that they flip forever between two configurations without any energy input, and that this idea was controversial because it seemingly violates the laws of physics. But since then, several research groups have created time crystals in the laboratory that contain quantum interiors.
