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.

A new technical paper titled “Penning micro-trap for quantum computing” was published by researchers at ETH Zürich, Leibniz Universität Hannover, and Physikalisch-Technische Bundesanstalt. “Trapped ...

The experimental setup of the ETH researchers. The trap chip is located inside the container underneath the silver cupola, in which a lens captures the light emitted by the trapped ions. Credit: ETH ...

Using oscillating electromagnetic field in ion traps limits the currently achievable number of qubits in quantum computers. Researchers at ETH have now created an ion trap on a microfabricated chip ...
