In a study published in npj Computational Materials, researchers showed that nitrogen-vacancy centers in diamond (a leading solid-state qubit platform) are energetically attracted to dislocations and retain or improve their quantum properties.
Nitrogen-vacancy centers self-align along a dislocation in diamond, leading to stable qubits with viable optical cycle and longer coherence time
Scientific Achievement
Using advanced first-principles simulations, we showed that nitrogen-vacancy centers in diamond, a leading solid-state qubit platform, are energetically attracted to dislocations and retain, or in some cases improve, their quantum properties.
Significance and Impact
This work opens a path toward scalable quantum interconnects exploiting dislocations in diamond and potentially other materials, offering a promising strategy for future solid-state quantum technologies.
Research Details
Unprecedented large-scale first-principles calculations, enabled by interoperable GPU-accelerated, massively parallel codes developed within MICCoM, made it possible to accurately predict the complex quantum properties of defects at dislocations
