Dynamic resonance fluorescence in solid-state cavity quantum electrodynamics
Shunfa Liu, Chris Gustin, Hanqing Liu +7
The coherent interaction between a two-level system and electromagnetic fields serves as a foundation for fundamental quantum physics and modern photonic quantum technology. A prof…
Improving On-Demand Single Photon Source Coherence and Indistinguishability Through a Time-Delayed Coherent Feedback
Gavin Crowder, Lora Ramunno, Stephen Hughes
Single photon sources (SPSs) are an essential resource for many quantum information technologies. We demonstrate how the inclusion of time-delayed coherent feedback in a scalable w…
Generalized Dicke model and gauge-invariant master equations for two atoms in ultrastrongly-coupled cavity quantum electrodynamics
Kamran Akbari, Will Salmon, Franco Nori +1
We study a generalization of the well-known Dicke model, using two dissimilar atoms in the regime of ultrastrongly coupled cavity quantum electrodynamics. Our theory uses gauge inv…
Probing dressed states and quantum nonlinearities in a strongly coupled three-qubit waveguide system under optical pumping
Sofia Arranz Regidor, Stephen Hughes
We study a three-qubit waveguide system in the presence of optical pumping, when the side qubits act as atomlike mirrors, manifesting in a strong light-matter coupling regime. The…
Gauge-invariant theory of truncated quantum light-matter interactions in arbitrary media
Chris Gustin, Sebastian Franke, Stephen Hughes
The loss of gauge invariance in models of light-matter interaction which arises from material and photonic space truncation can pose significant challenges to conventional quantum…
All-optical Tuning of Indistinguishable Single-Photons Generated in Three-level Quantum Systems
Łukasz Dusanowski, Chris Gustin, Stephen Hughes +2
Resonance fluorescence of two-level quantum systems has emerged as a powerful tool in quantum information processing. Extension of this approach to higher-level systems provides ne…
