Scientists have created the first complete design for a quantum version of a pendulum clock using a single atom, mirrors and light. The device could advance understanding of timekeeping at the quantum scale.

Matteo Brunelli at Collège de France and colleagues developed a mathematical model that replicates the key elements of a traditional grandfather clock with quantum components. Their design features a cavity formed by two facing mirrors, one of which oscillates, along with an atom that transitions between energy states and emits photons to drive the motion. The atom serves as the escapement mechanism, ensuring stable ticks without external control.

Study explores quantum clocks ticking at multiple speeds

Physicists have published research proposing that a single clock could tick both faster and slower at the same time due to quantum effects. The work combines relativity and quantum mechanics in a novel way. Researchers say advances in atomic clock technology may soon allow the idea to be tested in the lab.
