KurzbeschreibungThis course covers the physics of systems where harmonic oscillators are coupled to spin systems, for which the 2012 Nobel prize was awarded. Experimental realizations include photons trapped in high-finesse cavities and ions trapped by electro-magnetic fields. These approaches have achieved an extraordinary level of control and provide leading technologies for quantum information processing.
LernzielThe objective is to provide a basis for understanding the wide range of research currently being performed on fundamental quantum mechanics with spin-spring systems, including cavity-QED and ion traps. During the course students would expect to gain an understanding of the current frontier of research in these areas, and the challenges which must be overcome to make further advances. This should provide a solid background for tackling recently published research in these fields, including experimental realisations of quantum information processing.
InhaltThis course will cover cavity-QED and ion trap physics, providing links and differences between the two. It aims to cover both theoretical and experimental aspects. In all experimental settings the role of decoherence and the quantum-classical transition is of great importance, and this will therefore form one of the key components of the course. The topics of the course were cited in the Nobel prize which was awarded to Serge Haroche and David Wineland in 2012.

Topics which will be covered include:

Cavity QED
(atoms/spins coupled to a quantized field mode)
Ion trap
(charged atoms coupled to a quantized motional mode)

Quantum state engineering:
Coherent and squeezed states
Entangled states
Schrodinger's cat states

Decoherence:
The quantum optical master equation
Monte-Carlo wavefunction
Quantum measurements
Entanglement and decoherence

Applications:
Quantum information processing
Quantum sensing
