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 ...

a naturally occurring 2D triangular crystal lattice of hundreds of spin-1/2 particles (Beryllium ions stored in a Penning trap), a computationally relevant scale more than an order of magnitude larger ...

Trapping ions with static magnetic and electric fields instead of an oscillating electromagnetic field could make it easier to use ions as building blocks for quantum computers. The new approach, ...
