Nanodiamond sensors allow for complete surveillance at the cell level

In bulk diamond, NVCs can store photons, along with the quantum data they might carry, for many milliseconds. New techniques have recently enabled nano-sized diamond structures to be self-assembled by joining them to ring-shaped molecules known as SP1 proteins. The traditional problem with trying to scale down to nanodiamonds has been that they show poor spin coherence — typically in the microsecond range. Now researchers at the University of Cambridge have found a way to protect NVC spins in finely-milled synthetic diamonds, and perform coherence measurements at high resolutions.
