One of the biggest challenges in modern physics is uniting quantum mechanics and general relativity. A new experiment may ...

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

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 ...

Get Instant Summarized Text (Gist) Using two distinct time scales in quantum clocks—analogous to second and minute hands—enables exponential gains in accuracy relative to entropy and energy ...

In their model, the clock doesn't measure each individual tick. Instead, it tracks the overall flow of time by letting quantum excitations (tiny packets of energy) move across a system without ...

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

Next-generation atomic timekeeping techniques could push new frontiers in quantum physics, according to a new study.. Atomic clocks are essential elements in GPS and other navigation systems ...

As Make puts it, the atomic clock is old and busted. The quantum-logic clock from National Institute of Standards and Technology, keeping time 100,000 times more accurately than its predecessor ...

The quantum-logic clock, which detects the energy state of a single aluminum ion, keeps time to within a second every 3.7 billion years. The new timekeeper could one day improve GPS or detect the ...

Tick tock: Artist's impression of a quantum clock. (Courtesy: Alexander Rommel/TU Wien) The second law of thermodynamics demands that if we want to make a clock more precise – thereby reducing the ...

The Quantum Clock - a first for the UK - is expected to be rolled out in four years time and it will help Royal Navy ships and Royal Air Force planes to navigate ...

An almost dissipation-free quantum clock. The idea for this new kind of clock came out of a meeting at the Quantum Thermodynamics Conference in Vienna in 2023.
