Atomic-scale defects in crystals can make excellent quantum memories that can be written and read out using lasers, and could form the basis of future quantum communications and computing systems.

A series of experiments across multiple research groups has shown that deliberately implanting atomic-scale defects into ordinary silicon can turn the world’s most common semiconductor into a source ...

You probably thought of a clear and flawless gemstone used in jewellery. But to a physicist, a perfect diamond might actually be quite boring. Something magical happens when the diamond is just a ...

Something seems to be missing from the universe, and the favored model of physics calls it “dark matter” – but despite a century of searching, it remains a no-show. A new paper proposes an alternative ...
