Scientists connect time crystal to real device in quantum breakthrough

A strange kind of matter that ticks forever without energy input has just taken a major leap toward real-world use. Known as a time crystal, this quantum system repeats its motion endlessly-like a clock that never winds down-and scientists have now managed to connect it to an external device for the first time. By linking the time crystal to a tiny mechanical oscillator, researchers showed they can actually control its behavior, opening the door to powerful new technologies.
