Phys.org  August 26, 2024 Coherent quantum control is an essential tool for understanding and mitigating decoherence. Characterizing and controlling orbital states is a central challenge for quantum networking, where optical coherence is tied to orbital coherence. Researchers at Cornell University studied resonant multi phonon orbital Rabi oscillations extracting the strength of the orbital-phonon interactions and the coherence of the acoustically driven orbital states. They reached the strong-driving limit, where the physics was dominated by coupling induced by the acoustic waves. They found agreement between their measurements, quantum master-equation simulations, and a Landau-Zener transition model in the strong-driving limit. They modeled […]
