Scientists Uncover a Hidden Energy Cost in Quantum Timekeeping

Researchers found that measuring a quantum clock consumes vastly more energy than the clock’s own operation—up to a billion times more. By tracking single-electron jumps, they discovered that the act of turning quantum events into classical data drives most of the entropy. This makes measurement, not ticking, the true thermodynamic cost of quantum timekeeping. Quantum […]
