Controlling quantum defects in graphene

The development of quantum technologies relies on the ability to fabricate and engineer materials with robust quantum properties. The controlled introduction of defects in semiconductors is one of the most promising platforms under development. With the capability to precisely position point defects (five-membered rings) in the graphene honeycomb lattice, Lombardi et al. explored recent theoretical work suggesting that such defects should display enhanced quantum properties (see the Perspective by von Kugelgen and Freedman). The spin-bearing properties of the defects and the engineered control of their interactions open up exciting possibilities for graphene-based spintronics and quantum electronics.
