Quantum computing

Diamond wedding for spin couple

Observing coherent coupling between two quantum objects in the solid state is hard enough at millikelvin temperatures. Now, this has been achieved at room temperature — using nitrogen defects in diamond — opening up an avenue to practical quantum computing.

Figure 1: Two antipodal approaches to quantum computing could be achieved with nitrogen defects in diamond, both strengthened by the impressive room-temperature spin-coherence lifetimes and coherent spin–spin coupling presented in ref.1.
