The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic ...

This can lead to elastic interactions, where atoms maintain their identity, or inelastic collisions, where atoms break into ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

Atoms of different elements have different numbers of protons, neutrons and electrons. For example, a hydrogen atom has one proton, one electron and zero neutrons, while uranium has 92 protons ...

Unlike classical bits, however, qubits (which might be molecules, atoms, photons ... Specifically, they show how to measure electron spin superpositions, a quantum mechanical property that ...

A qubit can be any quantum object with two or more states—for example, a single electron that can be in a spin-up or spin-down ... engineered with dopant atoms—impurities intentionally added ...

The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of ...
