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…

Milli-Hertz Frontier: Compact Detectors Expand Gravitational Wave Access
Overview: A new approach to the gravitational wave mid-band The scientific community has long sought to fill the gravitational wave spectrum’s mid-band, a stretch between high-frequency terrestrial detectors and low-frequency pulsar timing arrays. Researchers from the University of Birmingham and the University of Sussex have proposed and developed a compact, ground-based detector that targets the…
