TL;DR: In this article, a single photon with near-unity indistinguishability was generated from quantum dots in electrically controlled cavity structures, which allowed for efficient photon collection while application of an electrical bias cancels charge noise effects.

Strong coupling of a spin ensemble to a superconducting resonator.
Yuimaru Kubo,Florian R. Ong,Patrice Bertet,Denis Vion,Vincent Jacques,D. Zheng,A. Dréau,Jean-François Roch,Alexia Auffèves,Fedor Jelezko,Joerg Wrachtrup,Marie-France Barthe,Philippe Bergonzo,Daniel Esteve +13 more
TL;DR: A quantum circuit in which an ensemble of electronic spins is coupled to a frequency tunable superconducting resonator and the appearance of a vacuum Rabi splitting in the transmission spectrum of the resonator when its frequency is tuned through the nitrogen-vacancy center electron spin resonance.

TL;DR: The complete Wigner function W of the vacuum and of a single-photon state for a field stored in a high-Q cavity is measured and the nonclassical nature of the single- photon field is exhibited by a region of negative W values.

Strain-mediated coupling in a quantum dot-mechanical oscillator hybrid system
Inah Yeo,Pierre-Louis de Assis,Arnaud Gloppe,Eva Dupont-Ferrier,Pierre Verlot,N. S. Malik,Emmanuel Dupuy,Julien Claudon,Jean-Michel Gérard,Alexia Auffèves,Gilles Nogues,Signe Seidelin,Jean-Philippe Poizat,O. Arcizet,Maxime Richard +14 more
TL;DR: This work presents the experimental realization of a monolithic solid-state hybrid system governed by material strain: a quantum dot is embedded within a nanowire that features discrete mechanical resonances corresponding to flexural vibration modes.

TL;DR: In this paper, the authors showed that an intimate relationship exists between information and thermodynamics, and showed that a microwave cavity can encode quantum information about a superconducting qubit and convert information into work by powering up a propagating microwave pulse by stimulated emission.
