About QUINST

Quantum mechanics is at the heart of our technology and economy - the laser and the transistor are quantum devices - but its full potential is far from being realized. Recent technological advances in optics, nanoscience and engineering allow experimentalists to create artificial structures or put microscopic and mesoscopic systems under new manipulable conditions in which quantum phenomena play a fundamental role.

Quantum technologies exploit these effects with practical purposes. The objective of Quantum Science is to discover, study, and control quantum efects at a fundamental level. These are two sides of a virtuous circle: new technologies lead to the discovery and study of new phenomena that will lead to new technologies.

Our group's aim is  to control and understand quantum phenomena in a multidisciplinary intersection of  Quantum Information, Quantum optics and cold atoms, Quantum Control, Spintronics, Quantum metrology, Atom interferometry, Superconducting qubits and Circuit QED and Foundations of Quantum Mechanics.

Title: Revisiting Cavity Quantum Electrodynamics with solid-state systems: the N-emitter case

Abstract
We study the properties of a cavity interacting with many emitters, paying attention to the effects of a large inhomogenous broadening in the emitters frequencies. Our model can represent a wide range of systems in solid-state physics, like NV centers coupled to a superconducting cavity, or quantum dots coupled to a semiconducting optical cavity. Based on the transmission spectra and the dynamics of the emitters-cavity coupling, we revisit the notion of strong and weak coupling regime, and analyse the potential of such systems to implement a quantum memory.
