In a breakthrough study led by St John's Fellow Mete Atature, scientists have revealed the coherence, or the visibility lifespan, of the spin of an electron in an emerging colour centre in diamond. This could provide a potential component for future quantum networks.
A new study has successfully measured the coherence of electron spin – the period of time in which the particle’s elusive quantum state can be read and manipulated – for an electron trapped in conditions that could form the basis of a future quantum internet.
