ABSTRACT: 

This lecture consists on two parts. In the first one I will review the theory of superconducting circuits, to explain how these devices can be used to simulate the quantum mechanical behavior of photons and artificial atoms or qubits. We will explore the most common types of qubits, the fundamentals of circuit-QED, and rudimentary notions on the theory of measurement in these devices.  In the second part, I will explain how to combine these circuits to explore quantum optical phenomena with confined and propagating photons. We will discuss the ultra-strong coupling regime, and how this affects phenomena such as Rabi oscillations and spontaneous emission, the interaction with propagating photons, or the interaction between photons themselves. If time permits, we will also skim some ongoing applications of these devices to quantum simulation and the engineering of superconducting quantum networks.

BIO:
Juan José García Ripoll graduated at Universidad Complutense de Madrid in 2001, after finishing a PhD on ultracold atom physics and Bose-Einstein condensation. From 2001 to 2006 he worked at the Max-Planck Institute for Quantum Optics, contributing to the design of quantum computers, quantum simulators and many-body computational methods based on tensor networks. Since 2008 he works at CSIC, where he now coordinates a research group that explores both the implementation of quantum technologies as well as the development of algorithms and applications of these technologies in optimization, simulation and machine learning.
