The fragility and laws of quantum physics generally make the characterization of quantum systems time‑consuming. Furthermore, ...

The properties of a quantum material are driven by links between its electrons known as quantum correlations. A RIKEN ...

By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in ...

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 ...

Quantum key distribution promises ultra-secure communication by using the strange rules of quantum physics to detect eavesdroppers instantly. But even the most secure quantum link can falter if the ...

A new study reveals how intertwined forms of frustration in quantum materials can give rise to unconventional magnetic states.

The study shows that in quantum devices, reading a clock consumes far more energy than running it. This insight will help ...

An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

By squeezing terahertz light beyond its usual limits, researchers have exposed hidden quantum "jiggles" inside a ...

Graphic illustrating the difference in energy between running a quantum clock (left: a single electron hopping between two nanoscale regions) and reading the ticks of the clock (right). The energy ...

Henry Yuen is developing a new mathematical language to describe problems whose inputs and outputs aren’t ordinary numbers.

As with many information security professionals, I am a proponent of the so-called “defense in depth” approach to security—using multifaceted technologies and approaches to layer defenses and minimize ...
