Topics, Program and Report

The course deals with RF excitations in doped crystals.

During the first two days of the course, the students give short presentations of their projects and discuss the topics and skills they want to learn.

The lecturers of the course are Dieter Suter (TU Dortmund) and Matthew Sellars (Australian National University).

The lecturers present lectures on topics from quantum computing, crystal growth, and spectroscopy of rare earth ions, interactions in Rare Earth Ion doped crystals, Raman heterodyne spectroscopy and dynamical decoupling. During the week the group and the teachers decide to take some additional lectures on Bloch equations and rotating frames, so lectures on those topics are added.

A major part of the course includes experimental work which concentrates on radio-frequency (RF) technology: sources for RF excitations and measurement, modulation, demodulation and filtering of RF-signals. The students learn to build simple circuits with active and passive components and optimal detection of weak, time-dependent signals. Also tuned radio-frequency circuits are designed and tested. Finally, an important spectroscopic instrument, an optical heterodyne system is constructed and tested. On this basis, the students do important noise studies. They calculate the shot noise limit for this setup and compare it with the measured noise. Similarly, the amount of thermal noise for a given setup is calculated and compared to the experimentally achieved noise background.

The results are summarized by the participants and presented at a meeting on the last day of the course.
