Philippe GRANGIER

法国光学研究所 主任研究员

Philippe Grangier is head of the Quantum Optics group at Institut d'Optique in Palaiseau, France, and Professor at Ecole Polytechnique. He realized many quantum optics experiments during the 80’s and 90’s, then from 2000 he has been working in Quantum Information Processing, using e.g. single atom qubits in microscopic optical tweezers, quantum cryptography using single photons or continuous variables, entanglement control in atomic and photonic quantum states. He authored more than 200 publications, and his achievements have been recognized by many national and international awards, including a European ERC grant. He has been the coordinator of several large European projects on Quantum Optics and Quantum Information Processing, and he is now leading a large Quantum Technologies network in the Paris area (SIRTEQ, Région Ile de France).

Lecture : « Optical quantum engineering, from fundamentals to applications »
In this course we will start from basic quantum mechanics and introduce progressively qubits, entanglement, and Bell's inequalities; some details will be given about Aspect's experiments realized in the 1980's at Institut d'Optique, as well as on the recent « loophole free Bell tests » realized in 2015. Then we will point out the links between entanglement, quantum measurement, and quantum gates, and illustrate these ideas using some simple examples. Finally these ideas will be applied to quantum optics experiments with Gaussian and non Gaussian states, quantum cryptography, and possible future quantum networks. 

Pierre PILLET

巴黎-萨克雷高等师范学院 教授

Pierre Pillet graduated from the Ecole Normale Supérieure (1973-1977), where he obtained his PhD degree (Thèse de troisième cycle) and the “Agrégation of Physics” both in 1977. In 1977 he joined the Centre National de la Recherche Scientifique, and worked at Laboratoire Aimé Cotton. In 1982 he got his “Thèse d’Etat” in Physical Sciences (Tenure) at University Paris-Sud. In 1982-1983 he joined the Stanford Research Institute (SRI International) at Menlo Park (California). He is today Director of Research (Exceptional class) in CNRS. He has headed the Laboratoire Aimé Cotton from 2001 to 2011, then he has headed the Laboratory of Excellence “Physics Atom Light Matter” (LabEx PALM of University Paris-Saclay) from 2011 to 2015. He has been Professor (part time) at Ecole Polytechnique from 1992 to 2006. Pierre Pillet is recognized for his pioneering works and developments in cold molecules and in cold Rydberg atoms.

Lecture: « Rydberg physics, from Rydberg atoms to Rydberg matter »

Rydberg atoms make a bridge for understanding the atoms in extreme conditions. In the past, they have already allowed to study fascinating situations of quantum chaos or to realize gedanken experiments as quantum non-demolition measurement… Today cold Rydberg atoms offer a real and novel opportunity for quantum simulation and quantum engineering, leading many research groups to develop activities in the domain. During these lectures, we will introduce the theoretical basis for physics of Rydberg atoms: quantum defect theory, Rydberg atoms in the presence of external fields, collisions… We will then present the main exaggerated properties of Rydberg atoms, develop the experimental approaches, and described a few examples of applications of Rydberg atoms. We will finally introduce the cold Rydberg atoms which allowed to prepare frozen gases in very strong interaction. We will present a few applications chosen among many recent works in few-body and many-body physics.

Fabien BRETENAKER

巴黎-萨克雷高等师范学院 教授

Fabien Bretenaker graduated from Ecole Polytechnique, France, in 1988. He received his PhD degree from University of Rennes, Rennes, France, in 1992 while working on ring laser gyroscopes for Sagem. He joined the Centre National de la Recherche Scientifique, Rennes, in 1994 and worked in Rennes until 2002 on laser physics and nonlinear optics. In 2003, he joined the Laboratoire Aimé Cotton, Orsay, France, working on nonlinear optics, laser physics, quantum optics, and microwave photonics. He is also a part time professor in Ecole Polytechnique, Palaiseau, France, and adjunct professor in Ecole Normale Supérieure Paris Saclay, Cachan, France and in Raman Research Institute in Bangalore, India. 

Lecture : « Coherent processes in atomic systems and application to optical quantum memories »

This course will start from basic quantum mechanics and will introduce the semiclassical description of light-atom interaction, based on the density operator formalism. After having reviewed some important aspects of the interaction of light with two level atoms, we will introduce coherent effects leading to the appearance of narrow resonances, such as coherent population oscillations (CPO) and electromagnetically induced transparency (EIT). We will discuss how those effects can or cannot be used to store light and to build quantum memories.

Tommaso ROSCILDE

里昂高等师范学院 教授

After obtaining his PhD at the University of Pavia (Italy) in 2003, Tommaso Roscilde has been a postdoctoral research associate at the University of Southern California (Los Angeles) and at the Max-Planck Institute for Quantum Optics, before joining the Laboratoire de Physique” of the Ecole Normale Supérieure de Lyon as a faculty member in 2008. He works on the theory of quantum condensed matter, with special emphasis on quantum simulation of many-body systems and many-body quantum entanglement. 

Lecture : « Quantum correlations and entanglement : from theory to applications »

This lecture will introduce the notion of quantum entanglement and correlations, and practical ways to detect them both in theory as well as in experiments. We shall discuss relevant examples in which entanglement represents the crucial ingredient powering future quantum technologies.

Pierre-François COHADON

巴黎高等师范学院 教授

After early quantum optics work in the field of Optical Parametric Oscillators, Pierre-François Cohadon joined what has become the Optomechanics and Quantum Measurement group at Laboratoire Kastler Brossel in 1996 to start graduate work. He was involved in the pioneering experiments performed at LKB: demonstration of feedback cooling of a mechanical resonator, demonstration of intracavity radiation pressure cooling, proof-of-principle demonstration of optomechanical correlations... For a few years, he has been involved as well in the Virgo project for the detection of gravitational waves, where he is in charge of radiation-pressure dynamical effects and the use of squeezing to further increase the sensitivity of Advanced Virgo.

Lecture : « Quantum Optomechanical Measurements »

The lecture will explore classical and quantum sensitivity limits in mechanical experiments, with a particular emphasis on gravitational-wave detection and atomic force microscopy. After an introduction to signal processing and noise in physics, we will explore two noise sources of utmost importance in high-sensitivity experiments: mechanical thermal noise and quantum optical noise. We will see how experiments are designed to limit the impact of thermal noise, and how the quantum noise of light limits the sensitivity of interferometric measurements. We will also discuss different techniques (squeezing, QND measurements...) to beat quantum limits.
