"One current method to narrow laser linewidth uses Brillouin lasers, where sound waves interact with light; but the effect is relatively weak, typically narrowing by only tens to hundreds of times," ...

A test using atomic clocks will watch superpositions ride Earth’s curved space-time and see if Einstein can play nice with ...

Optical clocks are typically evaluated on two levels — accuracy (how close a clock comes to measuring the ideal “true” time, ...

Possibly originating with the English poet Geoffrey Chaucer's "time and tide wait for no man," the idea that time waits for ...

Atomic clocks are our most precise timekeepers, with the best ones keeping time to within one second in 15 billion years. But there’s always room for improvement, as researchers at MIT have now ...

Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum ...

However, aluminum is tricky. The element is difficult to measure with lasers, as well as cool to absolute zero. But when ...

Researchers affiliated with the Q-NEXT quantum research center show how to create quantum-entangled networks of atomic clocks and accelerometers—and they demonstrate the setup's superior, high ...
