Predicting spin-qubit candidates now includes phonon effects
High-throughput screening for spin-qubit materials now benefits from a streamlined first-principles framework, simplifying calculations of phonon effects.
Researchers have derived a compact, tractable closed-form formula in the low-temperature limit for calculating non-radiative transition rates, streamlining the computational steps required to include phonon contributions to both radiative and non-radiative processes. Assessing color centers typically requires complex calculations incorporating phonon effects; this new method simplifies the original summation-based expression by replacing perturbative energy evaluations with a simpler computation. The methodology was successfully applied to impurity-vacancy defects in 4H-SiC, demonstrating its versatility for use with a broad range of material systems beyond silicon carbide. This advancement promises to accelerate the identification of promising solid-state spin defects for quantum technologies. A newly developed…
