Our research group focuses on advancing quantum dynamics and quantum control, with a particular emphasis on qubit manipulation and many-qubit systems to enable fault-tolerant quantum computing. We specialize in dynamical quantum error correction, including techniques such as robust quantum control, error correcting quantum circuit, error correction code (with particular focus on dynamical codes) to enhance the reliability of quantum computations. By bridging theoretical insights and practical implementations, our work spans a broad spectrum of quantum mechanics, aiming to accelerate the transition from foundational research to real-world applications.
Our research has the potential to revolutionize industries such as cryptography, drug discovery, and materials science by delivering innovative quantum solutions. To achieve this, we investigate developing advanced quantum control tools, robust simulation software, quantum algorithm tailored for realistic physical systems including superconducting qubits, quantum dot qubits, etc. Through quantum simulations, we model complex quantum systems, deepening our understanding of quantum behaviors while creating new computational tools for improved performance. Additionally, we are designing quantum algorithms for distributed quantum systems, harnessing their unique properties to push the boundaries of advanced computing.
Beyond quantum computing, we explore quantum sensing technologies for ultra-precise measurements. Our projects include the development of sensors for magnetic and electric fields, as well as applications in detecting weak electromagnetic signals, cosmic rays, and gravitational waves.
We also explore novel quantum device mechanisms, particularly focusing on the underlying quantum dynamics. One examples is the nonlinear dynamics in Josephson circuits, we investigate phenomena such as frequency combs, and quantum-classical transitions. By studying these complex dynamical systems, we aim to develop new approaches for quantum information processing and control potentially leading to new applicable devices such as quantum signal generator. This research area combines fundamental physics with practical applications, leading to innovations in quantum device engineering and quantum signal processing. Our investigations into nonlinear quantum dynamics not only advance our theoretical understanding but also contribute to the development of next-generation quantum technologies.
Through these interdisciplinary efforts, we aim to drive innovation in quantum technology, transforming science, industry, and society.
