Quantum timekeeping has reached a new threshold, with trapped-ion clocks now accurate to the 19th decimal place and a ...

The research team used two distributed sensors and leveraged two quantum resources for increasing detection sensitivity: ...

At the smallest scales of matter, nature behaves in ways that feel almost counterintuitive. Individual particles follow simple rules, but when they interact together, entirely new behaviors can ...

Are the mysteries of quantum mechanics finally starting to crack, or are we just getting better at asking sharper questions? Since the 2022 Nobel Prize in Physics honored experiments on quantum ...

Current lasers can introduce phase noise that causes errors in quantum computing. Better spectral purity will also enhance atomic clocks, which underpin GPS navigation and may soon enable new ...

The Pauli exclusion principle is a cornerstone of the Standard Model of particle physics and is essential for the structure and stability of matter. Now an international collaboration of physicists ...

On 9 July 1925, Heisenberg sent a paper titled ‘Quantum-theoretical re-interpretation of kinematic and mechanical relations’ to Max Born, whom he was assisting at that time, and Born sent the paper to ...

They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or ...

Time feels steady and familiar in daily life, but at the quantum level it becomes slippery. That puzzle now has a fresh twist thanks to new research led by physicists at École Polytechnique Fédérale ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...
