Some people claim that quantum physics is too arcane and remote to have practical applications, but modern life would be impossible without our understanding of the quantum nature of light and matter.

The first direct observation of the orbital structure of an excited hydrogen atom has been made by an international team of researchers. The observation was made using a newly developed “quantum ...

Quantum mechanics is simultaneously beautiful and frustrating. Its explanatory power is unmatched. Armed with the machinery of quantum theory, we have unlocked the secrets of atomic power, divined ...

Consider a hydrogen atom. You need to track one electron and one proton, ... And quantum mechanics can track this sort of correlation via the entanglement of two qubits.

The bubbling, raucous quantum vacuum distorts the shape of every hydrogen atom in the universe, and it distorts antimatter "antihydrogen" too. Mysterious 'antihydrogen' particles reveal uncanny ...

Quantum mechanics 100 years on: ... Pauli’s successful calculation 5 of the hydrogen atom spectrum using the scheme in December that year was widely regarded as a vindication of the effort.

Tauonium, composed of a tauon and its antiparticle, has a Bohr radius of only 30.4 femtometers (1 femtometer = 10-15 meters), approximately 1/1,741 of the Bohr radius of a hydrogen atom.
