Quantum optics and quantum information
Summary
This lecture describes advanced concepts and applications of quantum optics. It emphasizes the connection with ongoing research, and with the fast growing field of quantum technologies. The topics cover some aspects of quantum information processing, quantum sensing and quantum simulation.
Content
1. Introduction
Review of two-level systems and harmonic oscillators.
2. Entanglement, decoherence and measurements
Density matrix of bipartite systems, entanglement, entanglement entropy, generalized measurements, system-meter description and POVMs, completely positive maps and Kraus theorem, quantum channels
3. Open quantum systems
Lindblad master equation, fundamental examples: Optical Bloch equations, damped harmonic oscillator
4. Mechanical effects of light and laser cooling
Motional effects on light-matter interactions, Doppler and recoil shifts, semi-classical forces on the two-level atom, Doppler cooling and magneto-optical traps, sideband cooling.
5 - 6. Two topics chosen among:
- Trapped ions quantum logic
- Rydberg quantum logic
- Collective effects in light-matter interactions and quantum metrology
- Digital and analogue quantum simulation
Keywords
Quantum technology, quantum computing, quantum simulation, quantum optics, laser cooling, quantum measurement, quantum electrodynamics, quantum devices
