Sensing and Computing with Emerging Technologies

 Series:  CQuIC Seminars
 Abstract:  In the human body, sensory systems send information to the brain, and the information processed in the brain allows us to perceive the real world. Likewise, sensing and computing play an important role in our daily lives and have evolved through emerging technologies. Recent research trend in emerging technologies will be presented, including quantum sensing, integrated photonics, heterogeneous integration, high-performance computing, artificial intelligence (and its hardware accelerator) and quantum computing. Quantum sensors show high performance in the laboratory and have been used for applications in medical imaging, surface science, anomaly detection, map matching, positioning, navigation, and timing. In particular, we demonstrated a grating magneto-optical trap (GMOT) with a microfabricated grating chip, high data-rate GMOT operation, and a compact atom interferometer with a GMOT for the ruggedization of the sensor head in dynamic environments. For the miniaturization of the sensor head and laser system, we built the compact sensor head using custom vacuum packaging and fixed optical components, and configured the compact laser system using fiber-coupled photonic components compatible with integrated photonics. Additionally, we realized the photonic-integrated-circuit based laser system for light pulse sequence and demonstrated an atom interferometer.Acknowledgement: This work was supported by the Laboratory Directed Research and Development program at Sandia National Laboratories and is funded under the DARPA A-PhI program.
