Non-Markovian dynamics of a qubit due to single-photon by Ciccarello Francesco
Open Quantum Systems DATE: 17 July 2017 to 04 August 2017 VENUE: Ramanujan Lecture Hall, ICTS Bangalore There have been major recent breakthroughs, both experimental and theoretical, in the field of Open Quantum Systems. The aim of this program is to bring together leaders in the Open Quantum Systems community from a range of subfields, such as Mesoscopic Quantum Optics (Quantum Dot Circuit-QED systems), Cavity Optomechanics, Cavity-QED systems and many more. This field of hybrid quantum systems sits perfectly at the interface of condensed matter physics, quantum optics and non-equilibrium physics. Despite remarkable progress, there are still a large number of challenging and important experimental and theoretical questions thereby creating an immediate need for the program that is expected to facilitate vibrant discussions and collaborations among researchers from diverse fields. The main areas of focus in the program will be Mesoscopic Quantum Optics Hamiltonian and Quantum Bath Engineering Cavity Optomechanics Quantum Gases in Cavities Light-matter interactions in 1D continuum This program will be for active researchers in the areas and is designed to be especially beneficial for advanced graduate students and postdocs. There will also be some pedagogic lectures on the following topics: Cavity optomechanics - Aashish Clerk (Theory) - Week 2 Theory of solid-state quantum information processing - Guido Burkard (Theory) - Week 2 Non-Equilibrium physics of polaritons - Jacqueline Bloch (Experiment) - Week 2 Hybrid circuit quantum electrodynamics - Jason Petta (Experiment) - Week 1 Superradiance and the Dicke model - Jonathan Keeling (Theory) - Week 1 Quantum manifolds of steady states in driven, dissipative superconducting circuits - Michel Devoret (Experiment) - Week 2 Non-equilibrium behavior of quantum many-body systems - Stefan Kehrein (Theory) - Week 3 Mesoscopic quantum electrodynamics - Takis Kontos (Experiment) - Week 1 CONTACT US : [email protected] PROGRAM LINK: https://www.icts.res.in/program/oqs2017 Table of Contents (powered by https://videoken.com) 0:00:00 Start 0:00:04 Open Quantum Systems 0:00:11 Non-Markovian dynamics of a qubit due to single-photon 0:00:21 joint work with 0:00:46 in this talk 0:01:23 outline 0:02:34 waveguide QED 0:06:04 effects of time delays 0:07:01 our case study 0:08:12 what does "non-Markovian" mean? 0:09:29 what does NM mean? 0:11:34 quantum maps 0:13:21 dynamical map 0:14:21 when does Lindblad ME hold? 0:16:06 CP-divisibility 0:19:07 CP-divisibility and Master Equation 0:20:43 instances of CP-divisible non-Lindbladian dynamics 0:22:24 spontaneous emission of an atom 0:26:33 a qubit undergoing single-photon scattering 0:30:36 dynamical map 0:33:10 master equation 0:34:11 explicit computation of DM 0:36:15 CP-divisibility 0:38:51 non-Markovianity measure 0:45:21 conclusions 0:46:30 thank you! 0:46:38 Q&A
