“Quantum computers are going to revolutionize everything that relies on computers, which is basically all fields of science and technology,” predicts Hiroki Takahashi, assistant professor in ...

The energy states of electrons in an atom follow the laws of quantum mechanics: they are not continuously distributed but restricted to certain well- defined values – this is also called quantisation.
