Artist's Impression (IMAGE) University of New South Wales Caption This is an artist impression of an electron wave function (blue), confined in a crystal of nuclear-spin-free 28-silicon atoms (black), controlled by a nanofabricated metal gate (silver). The spin of the electron encodes a long-lived, high fidelity quantum bit. Credit Dr Stephanie Simmons, UNSW Australia.
