Light–matter interactions in quantum nanophotonic devices

TL;DR: Researchers propose a strong coupling system between excitons and chiral quasi-bound states in van der Waals metasurfaces, achieving high electric field enhancements and low loss, enabling control of coherent states via circular polarization of excitation light.

TL;DR: Collectively induced transparency and absorption in waveguide QED with Bragg atom arrays explores collective quantum phenomena in waveguide-coupled Bragg atom arrays. It demonstrates collectively induced transparency and absorption, and provides a way to manipulate collective quantum states and exotic optical properties.

TL;DR: Researchers design and investigate a dual-layer Si-ITO-dielectric hybrid plasmonic electro-absorption modulator, achieving enhanced performance with extinction ratio of 34.48 dB/μm and modulation frequency up to 1.72 THz at 1.55 μm wavelength.

TL;DR: In this paper, the authors review recent developments in measurement-based quantum computation with a view to both fundamental and practical issues, in particular the power of quantum computation, the protection against noise (fault tolerance) and steps towards experimental realization.

TL;DR: For example, in this article, Dirac's concept was used to explain the problem of interference in the creation of a defense against nuclear radii. And Dirac succeeded in constructing a theoretic framework to solve the problem.

TL;DR: The ultrastrong coupling (USC) regime is established when the light-matter interaction energy is a comparable fraction of the bare frequencies of the uncoupled systems as discussed by the authors.

TL;DR: In this article, a review describes progress towards the goal of multinode networks using the current generation of experiments, which have achieved unprecedented levels of atomic qubit control and light-matter coupling efficiencies.
