On the nanometre length scale, the non-radiative energy transfer process has an efficiency close to unity. Brenneis and colleagues now describe how this type of energy transfer can be used to electronically read-out the spin of nitrogen–vacancy centres in diamond, which are considered to play a fundamental role in new quantum information technologies. The diamond is placed only a few nanometres away from a graphene layer. Through non-radiative energy transfer additional charge carriers are generated in the graphene. These charges are detected as a current signal and provide information on the electron spin in the nitrogen–vacancy centre. The experiment was performed on a picosecond timescale, where the transfer efficiency is highest.
