MIT Advances Optical Atomic Clocks by Halving Quantum Noise with Global Phase Spectroscopy
Reaching New Heights in Timekeeping Every moment you rely on precise timing—whether checking a phone, making a digital payment, or navigating via GPS—you benefit from the extraordinary accuracy of atomic clocks. Today’s standard clocks track cesium atoms, ticking at about 10 billion times per second. But scientists are pushing toward optical atomic clocks that work…

Optical Atomic Clocks: Boosting Precision by Reducing Quantum Noise
Introduction: The Quest for Ever-Precise Time From checking the time on a smartphone to guiding navigation and delivering online payments, modern life depends on the extraordinary precision of atomic clocks. Traditional clocks rely on cesium atoms ticking billions of times per second, tracked by lasers at microwave frequencies. The next leap in timekeeping aims to…
