Researchers from the University of California, Santa Barbara and the University of Konstanz in Germany, led by David Awschalom reported a breakthrough in the use of diamond in quantum physics. The physicists were able to coax the fragile quantum information contained within a single electron in diamond to move into an adjacent single nitrogen nucleus, and then back again using on-chip wiring.

The discovery shows the high-fidelity operation of a quantum mechanical gate at the atomic level, enabling the transfer of full quantum information to and from one electron spin and a single nuclear spin at room temperature. The process is scalable, and opens the door to new solid-state quantum device development.

Here's David with a great introduction to Spintronics and Diamonds:
