Researchers have entangled atomic clocks allowing them to synchronise them more accurately. Such entangled clocks could be used study dark matter and gravity more precisely
7 September 2022
Two atomic clocks have been connected using quantum entanglement – a property that intrinsically links them so that changes in one instantaneously affect the other. The connection makes it easier to synchronise the clocks, which could be used to make more accurate measurements of dark matter and gravity.
Atomic clocks consist of atoms that are very precisely controlled by lasers. Each “tick” corresponds to a frequent and measurable change in energy that occurs in the atoms’ electrons. The result is …
