What’s the News: Physicists have worked out a new method of storing information in the quantum states of atoms in diamond crystals. The scientists linked the spin of individual nitrogen atoms in the diamond—impurities at the jewelry counter, but boons in the physics lab—to the spin of nearby electrons. They could form a quantum link between the spin of the nitrogen atom and the spin of a nearby electron, letting the electron store information more stably than if it were spinning on its own.
How the Heck:
