Time crystal


Did you see it? A quantum computer from Google has just built a time crystal. The name alone makes you shudder with pleasure as it evokes something between a good role-playing game and an episode of Doctor Who. More concretely, it is the discovery of a new state of matter that oscillates in space and time. Between the Covid vaccine and this kind of discovery, this kind of thing always makes me feel proud to be human. How a species from nothing manages to progress day after day, to thwart the blows of fate that put it in danger and to understand little by little the extraordinary universe that surrounds us... It is fabulous!
