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

Kyoto, Japan -- The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each ...

For building ultra-fast and secure quantum networks, quantum information must be stored and transferred reliably across long distances. A quantum register comprising numerous entangled nuclear spins ...

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