Formål
The lecture will lay the foundations of quantum optics and thus provide the basis for more specialised courses. In particular it will allow for a deeper understanding of the research on quantum communication with photons, the manipulation of individual atoms (quantum information), and the work with ensembles of ultracold atoms. It also provides an understanding of light matter interaction at the quantum level and the associated measurements.
Indhold
The first part of the lecture will contain:
-
Quantum theory of the electromagnetic field
-
Quantum states of light: Fock-states, coherent states, squeezed states
-
Atom light interaction: Rabi model, Bloch sphere (revision from AMO II)
-
Fully quantum mechanical description interaction: Jaynes-Cummings model
-
Classical and quantum coherence functions
-
Experimental realization of non-classical states of light and atoms
-
Experimental techniques for detection of quantum properties of light: Homodyne and heterodyne detection
The second part of the lecture will relate this deeper understanding of quantum optics to the research directions at IFA e.g.:
-
Laser Cooling: Doppler and sub-Doppler (polarization gradient) cooling
-
Atom Optics and atom interferometry (using Bloch sphere picture)
-
Quantum communication with few and individual photons
-
Realization of coherent coupling of quantum systems (e.g. cavity QED with trapped ions)
-
Experimental realization of single-photon sources
-
Measurement of correlation functions, e.g. BEC
