Traditional clocks, including quantum ones, rely on counting repeated, irreversible events, like a pendulum swinging or atoms jumping between energy levels. Every time one of these ticks happens, a ...

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 ...

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 physicists have tapped into a kind of ghostly interaction, known as entanglement, to improve the precision of optical atomic clocks, which measure time through the natural 'ticking' of atoms.

The best clock in the world has no hands, no pendulum, no face or digital display. It’s a jumble of lasers, wires and strontium atoms in Jun Ye’s lab at the National Institute of Standards and ...

Scientists have built a clock which is 37 times more precise than the existing international standard. The quantum-logic clock, which detects the energy state of a single aluminum ion, keeps time ...

Imagine building a better clock — with entangled atoms. Sound difficult? Not for Monika Schleier-Smith, associate professor of physics at Stanford University and 2020 MacArthur Fellow. Schleier ...

Though the effect is far too small to be noticeable to humans, this idea of quantum time dilation could have repercussions for high-precision quantum clocks. And crucially, ...

Quantum Network Would Be Most Precise Clock Yet A proposal claims that harnessing quantum entanglement could surpass the accuracy of any single atomic clock By Alexandra Witze , Nature magazine on ...

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 ...

The group’s new clock is made from a few dozen strontium atoms trapped in a lattice pattern. To improve the device’s performance, the team generated a type of ghostly interaction, known as quantum ...
