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.

Twisted Light Gives Electrons a Spinning Kick
Scientists seeking better methods for controlling the quantum interactions between light and matter demonstrated a novel way to use light to give electrons a spinning kick. In the journal Nature Photonics, they reported the results of an experiment, showing that a light beam can reliably transfer orbital angular momentum to itinerant electrons in graphene.
New Design Packs Two Qubits into One Superconducting Junction
Quantum computers are the basis of a growing industry. However, their technology isn’t standardized yet, and researchers are still studying the physics that goes into quantum devices. Even the most basic building blocks of a quantum computer—qubits—are still an active research topic. In an article in the journal Physical Review A, JQI researchers proposed a way to use the physics of superconducting junctions to let each function as more than one qubit.
