Students will give presentations in pairs on current experimental research in Quantum Information Processing. Each group has 30 min for the presentation plus 15 minutes for questions. A list of references for the presentation topics can be found below. Each presenter will be assessed by the other students, so that you can find out for yourselves how good your presentation skills are, and how you might improve them. The evaluation form is available here, information slides can be downloaded here.
