A series of quantum physics experiments and theoretical papers now suggest that heat can flow spontaneously from a cold ...

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

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 ...

Quantum physics may sound abstract, but Ph.D. candidates Kirsten Kanneworff and David Dechant show that quantum research can also be very concrete. Together, they are investigating how quantum ...

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

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

At the smallest scales of matter, nature behaves in ways that feel almost counterintuitive. Individual particles follow ...

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

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

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.
