Rayleigh scattering in an emitter-nanofiber-coupling system

Author(s): Shui-Jing Tang, Fei Gao, Da Xu, Yan Li, Qihuang Gong, and Yun-Feng Xiao

Scattering is a general process in both fundamental and applied physics. In this paper, we investigate Rayleigh scattering of a solid-state-emitter coupled to a nanofiber, by S-matrix-like theory in k-space description. Under this model, both Rayleigh scattering and dipole interaction are studied be…

Bell Correlations in Spin-Squeezed States of 500 000 Atoms

Author(s): Nils J. Engelsen, Rajiv Krishnakumar, Onur Hosten, and Mark A. Kasevich

Nonlocal correlations implied by quantum mechanics have been achieved to high statistical significance in an ensemble of half a million atoms, an increase by three orders of magnitude over previous results.

Interfacing Superconducting Qubits and Single Optical Photons Using Molecules in Waveguides

Author(s): Sumanta Das, Vincent E. Elfving, Sanli Faez, and Anders S. Sørensen

We propose an efficient light-matter interface at optical frequencies between a single photon and a superconducting qubit. The desired interface is based on a hybrid architecture composed of an organic molecule embedded inside an optical waveguide and electrically coupled to a superconducting qubit ...

Thermalization and Return to Equilibrium on Finite Quantum Lattice Systems

Author(s): Terry Farrelly, Fernando G. S. L. Brandão, and Marcus Cramer

Thermal states are the bedrock of statistical physics. Nevertheless, when and how they actually arise in closed quantum systems is not fully understood. We consider this question for systems with local Hamiltonians on finite quantum lattices. In a first step, we show that states with exponentially d...
