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…
Coupling Perovskite Quantum Dot Pairs in Solution using Nanoplasmonic Assembly
Hao Zhang, Parinaz Moazzezi, Juanjuan Ren +8
Perovskite quantum dots (PQDs) provide a robust solution-based approach to efficient solar cells, bright light-emitting devices, and quantum sources of light. Quantifying heterogen…
Optimizing the chiral Purcell factor for unidirectional single photon emitters in topological photonic crystal waveguides using inverse design
Eric Nussbaum, Nir Rotenberg, Stephen Hughes
We present an inverse design approach to significantly improve the figures-of-merit for chiral photon elements and quantum emitters in topological photonic crystal slab waveguides.…
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…
Using the Autler-Townes and ac Stark effects to optically tune the frequency of indistinguishable single-photons from an on-demand source
Chris Gustin, Łukasz Dusanowski, Sven Höfling +1
We describe how a coherent optical drive that is near-resonant with the upper rungs of a three-level ladder system, in conjunction with a short pulse excitation, can be used to pro…
