    Erbium Nanophotonic Resonators Achieve Ultra-High Q-Factors

    by Dr. DonovanApril 29, 2025
  • Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences and the OxideMEMS Lab at Purdue University have developed a system that uses atomic vacancies in silicon carbide to measure the stability and quality of acoustic resonators. These resonators are used in most smart phones, Wi-Fi and GPS systems to filter out noise that could degrade a signal. The researchers' system could also be used for acoustically-controlled quantum information processing, providing a new way to manipulate quantum states embedded in silicon carbide. This technique could be used in monitoring the performance of accelerometers, gyroscopes and clocks over their lifetime and has potential for hybrid quantum memories and quantum networking.
