Authors

Direct measurements reveal relaxation rates and phonon coupling in quantum dot molecules, suggesting enhanced entanglement potential.

Phonon-mediated relaxation rates exhibit pronounced resonances and anti-resonances, enhancing quantum state generation.
Rates vary from several tens of ns$^{-1}$ to tens of μs$^{-1}$, indicating strong phonon coupling effects.
Our kinetic model clarifies the relationship between phonon-assisted relaxation and radiative recombination mechanisms.
Anti-resonances may improve the lifetimes of unfavorable charge configurations, crucial for efficient spin-photon interfaces.

Lienhart et al. (2025) studied this question.
