Quantum Clocks and the Cost of Timekeeping
Why in the News? A new study in Physical Review Letters finds that in quantum clocks the main cost of timekeeping comes from measurement rather than the clockwork itself, reshaping ideas in quantum metrology. What are Quantum Clocks? Concept: Quantum clocks are timekeeping devices based on microscopic quantum systems whose transitions – atomic jumps, tunnelling… Continue reading Quantum Clocks and the Cost of Timekeeping
