About

Our group aims to theoretically AND experimentally investigate various quantum properties of light-matter interaction for applications in future optoelectronic devices, quantum information processing, and sensing. Moreover, we explore associated fundamental phenomena, such as many-body physics, that could emerge in such physical systems. Our research is at the interface of quantum optics, condensed matter physics, quantum information sciences, and more recently, machine learning.

    Quantum Simulation

    Given the slow but steady rise of quantum simulators, what are the hardware-efficient ways to implement chemical and physical models? How can we verify that we have implemented the right Hamiltonian? How can we efficiently characterize many-body states on such systems and measure them? Any quantum system is noisy, how can we find efficient ways to characterize and combat the noise?

  • Hero image for Strongly correlated electron–photon systems

    Strongly correlated electron–photon systems

    July 4, 2022

    In a Nature Perspective, we highlight a paradigm based on controlling light–matter interactions that provides a way to manipulate and synthesize strongly correlated quantum matter. Photon-mediated superconductivity, cavity fractional quantum Hall physics and optically driven topological phenomena in low dimensions are among the frontiers discussed in this Perspective.

  • Boson Sampling

    Boson Sampling for Generalized Bosons (Video)

    June 23, 2022

    Recent progress on quantum random sampling protocols such as random circuit sampling (interacting) and boson sampling (non-interacting) demonstrate an advantage of quantum information processing. Is there an intermediately interacting regime where the random sampling becomes intractable in a classical setting and becomes feasible on a quantum device? We found that such an intermediately interacting regime could be feasibly utilized by a generalization of current boson sampling protocols.
