About HQSR Lab
The Hybrid Quantum Systems Research Laboratory (HQSRL) at the Korea Research Institute of Standards and Science (KRISS) explores the fundamental physics arising from the hybridization of different quantum systems and their practical applications. Our research encompasses a variety of quantum device platforms, including superconducting microwave quantum circuits, nanophotonic devices, and nanoelectromechancial systems. We fabricate our devices using nanofabrication facilities at KRISS nanofab and perform device characterization with various microwave and optical tools under atmospheric and cryogenic conditions. Through these efforts, we aim to develop quantum transducers for microwave-to-optical frequency conversion, quantum phononic/acoustic devices, nonlinear superconducting microwave circuits, and NEMS-based photonic devices, paving the way for advancing quantum information processing and quantum sensing.
Research
Superconducting microwave circuits are essential elements for quantum information processing. We are exploring linear and nonlinear interactions of microwave photons at cryogenic temperatures.
Engineering mechanical vibrations at the nanoscale enable noval applications in classical and quantum information processing. We explore linear and nonlinear dynamics in nanomechanical systems and engineer their dynamics for novel opto- and electromechanical devices.
Photonic crystals enable tight confinement of light within nanoscale dimensions. We are interested in exploring such the interaction of such localized light and mechanical vibrations for novel quantum applications such as quantum transduction.
