Entanglement and quantum discord in the cavity QED models [PDF]

Heliyon
We investigate the quantum correlation between light and matter in bipartite quantum systems, drawing on the Jaynes–Cummings model and the Tavis–Cummings model, which are well-established in cavity quantum electrodynamics.

Cavity Quantum Electrodynamics with Carbon Nanotubes

, 2017
Carbon nanotubes are extensively investigated for their amazing mechanical and electronic properties. Optically, they are excellent candidates for on-demand single-photon sources because they can be electrically excited and they can emit anti-bunched light at room temperature in the telecoms bands. However, their emission efficiency is low, its origins

Chiral cavity quantum electrodynamics

Nature Physics, 2022
Cavity quantum electrodynamics, which explores the granularity of light by coupling a resonator to a nonlinear emitter, has played a foundational role in the development of modern quantum information science and technology. In parallel, the field of condensed matter physics has been revolutionized by the discovery of underlying topological robustness ...

Spontaneous Emission Enhancement of CdSe Quantum Dots Embedded in a Two-dimensional Photonic Crystal L3 Nanocavity

ARO-The Scientific Journal of Koya University, 2021
Two-dimensional photonic crystal nanocavities were designed to tailor cavity quantum electrodynamics. Enhancing the spontaneous emission of low-quality factor nanocavity with embedded CdSe quantum dots (QDs) emitters is the aim of this study.

Non-Markovian transient spectroscopy in cavity QED

Physical Review Research, 2022
We theoretically analyze measurements of the transient field leaving a cavity as a tool for studying non-Markovian dynamics in cavity quantum electrodynamics (QED).

Quantum-To-Classical Transition in Cavity Quantum Electrodynamics [PDF]

Physical Review Letters, 2010
The quantum properties of electromagnetic, mechanical or other harmonic oscillators can be revealed by investigating their strong coherent coupling to a single quantum two level system in an approach known as cavity quantum electrodynamics (QED). At temperatures much lower than the characteristic energy level spacing the observation of vacuum Rabi ...

Cavity-Quantum-Electrodynamical Toolbox for Quantum Magnetism [PDF]

Physical Review Letters, 2019
The recent experimental observation of spinor self-ordering of ultracold atoms in optical resonators has set the stage for the exploration of emergent magnetic orders in quantum-gas--cavity systems. Based on this platform, we introduce a generic scheme for the implementation of long-range quantum spin Hamiltonians composed of various types of couplings,

All-silicon quantum light source by embedding an atomic emissive center in a nanophotonic cavity

Nature Communications, 2023
Silicon is the most scalable optoelectronic material but has suffered from its inability to generate directly and efficiently classical or quantum light on-chip.

Gauge-independent emission spectra and quantum correlations in the ultrastrong coupling regime of open system cavity-QED

Nanophotonics, 2022
A quantum dipole interacting with an optical cavity is one of the key models in cavity quantum electrodynamics (cavity-QED). To treat this system theoretically, the typical approach is to truncate the dipole to two levels. However, it has been shown that
