– Quantum nanophotonics<\/u>
<\/strong>Our research investigates the interaction between quantum emitters and complex electromagnetic environments, particularly those that are open, dispersive, and absorbing. This area has attracted significant attention due to its potential for modifying emitter properties. Macroscopic quantum electrodynamics provides a powerful framework for quantizing the electromagnetic field within arbitrary open structures, including materials with dispersive and lossy characteristics. This approach is widely applied across various fields, from studying quantum emitter decay and cavity QED to quantum nanophotonics, dispersion forces, and fast electron scattering. Our work emphasizes advancing the Macroscopic QED model and developing robust computational methods to further these applications.<\/p>

– Circuit quantum electrodynamics (QCE)
<\/strong>Over the past 30 years, the drive to create superconducting quantum processors has led to the development of circuit quantum electrodynamics (circuit-QED), a theory that models quantum electrical circuits. These circuits are superconducting, with the Josephson junction playing a crucial role. Our research explores the quantum electrodynamics of systems comprising transmission lines connected to lumped circuits, which include both linear elements\u2014such as capacitors and inductors\u2014and nonlinear elements like Josephson junctions. We focus on advancing the quantum circuit electrodynamics model, developing equivalent circuits, and creating sophisticated computational methods.<\/p>
