Two atomic clocks have been linked utilizing quantum entanglement – a property that intrinsically hyperlinks them in order that modifications in a single instantaneously have an effect on the opposite. The connection makes it simpler to synchronise the clocks, which could possibly be used to make extra correct measurements of darkish matter and gravity.
Atomic clocks include atoms which are very exactly managed by lasers. Every “tick” corresponds to a frequent and measurable change in vitality that happens within the atoms’ electrons. The result’s …
