Keeping Time on Entropy’s Dime

An experiment with a nanoscale clock verifies that a clock’s entropy per tick increases as the clock is made more precise.

Entropy generally increases with each tick of time, so it is natural that a timekeeping device produces an uptick in entropy as it runs. Building on previous work with quantum clocks, researchers now show that a simple classical clock whose ticks are the vibrations of a heat-driven, nanometer-thick membrane generates more entropy as its precision is increased [1]. The experiments open a new line for exploring how nanomachines can convert random inputs into useful work.
