Research
We explore the quantum frontier of light–matter interactions in nanophotonic devices and low-dimensional quantum materials. Our mission is to understand, control, and harness light-matter interactions at length scales far below the wavelength of light. We develop nanophotonic platforms that enhance and manipulate light–matter interactions through tailored symmetries, geometries, and optical resonances. These efforts enable the creation of scalable quantum light sources, photonic quantum computing platforms, and energy-efficient optical information systems. At the same time, we pursue fundamental discoveries in condensed matter physics by using quantum states of light to probe many-body phenomena in quantum materials. By using nonclassical light spectroscopy, we seek to reveal hidden excitonic, spin, and correlated quantum states that are inaccessible to conventional optical measurements.
Photonic Quantum Systems for Communication, Computing, and Networking
Quantum technologies promise transformative advances in secure communication, distributed computing, and information processing. Realizing this vision requires scalable sources of quantum light, precise control over quantum states, and energy-efficient interfaces between photons and electrons. Our research focuses on engineering light–matter interactions at the nanoscale to create next-generation photonic quantum systems.
We develop nanophotonic platforms that enable deterministic single-photon emission, reconfigurable quantum state generation, and energy-efficient nonlinear and chiral photonic devices. By integrating advances in materials science, nanophotonics, and quantum optics, we seek to establish the foundational technologies for scalable quantum networks, fault-tolerant photonic quantum computing, and high-performance optical connectivity.

Nonclassical Light Spectroscopy of Low-Dimensional Quantum Materials
Low-dimensional quantum materials exhibit a rich landscape of many-body phenomena arising from strong Coulomb interactions, reduced dielectric screening, and quantum confinement. These systems host a variety of emergent excitations and correlated states—including dark excitons, interlayer excitons, exciton blockade, charge-density waves, spin waves, and collective quantum phases—that play central roles in their optical and electronic properties. However, many of these states remain hidden or difficult to access using conventional spectroscopy because classical light primarily probes single-particle excitations and linear optical responses.
Our research seeks to establish nonclassical light spectroscopy as a new frontier for exploring quantum matter. By leveraging entangled photons, correlated photon pairs, squeezed light, and other engineered quantum states of light, we aim to selectively excite, probe, and control many-body interactions in two-dimensional van der Waals materials and their heterostructures. These quantum optical probes provide access to higher-order correlations, collective excitations, and quantum pathways that are inaccessible to classical measurements, enabling new insights into excitonic correlations, moiré quantum phases, quantum magnetism, superconductivity, and nonequilibrium quantum dynamics.
