New Publication: Extending radiowave frequency detection range with dressed states of solid-state spin ensembles
We are thrilled to share our latest publication, funded by the Quench Project, showcasing significant advancements in extending the detection range of quantum sensors for radio wave signals! By utilizing continuous dynamic decoupling sequences, we have successfully achieved detection of frequencies that are approximately 10 times higher than those possible with conventional pulsed methods. This breakthrough has profound implications for improving chemical resolution in NV-based NMR spectroscopy.
📌 Key Highlights:
âž¡ Innovative Approach: Our research introduces a new continuous dynamical decoupling (CDD) scheme that employs dressed states of nitrogen vacancy (NV) ensemble spins within a microwave resonator.
âž¡ Expanded Frequency Detection: We demonstrate the ability to detect RF signals up to ~85 MHz, surpassing the limitations of traditional pulsed dynamical decoupling (PDD) protocols by nearly tenfold under the same conditions.
âž¡ Enhanced Capabilities: Implementing the CDD method in a heterodyne/synchronized protocol allows for high-frequency detection combined with exceptional spectral resolution.
