QSIT (FS 2015) - Students' presentations

Students will give presentations in groups up to 3 people 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. 

Currently the following students are assigned for a talk: Adrian Beckert, Amade Bortis, Viola Hansjakob, Vinzenz Vogel, Natascha Hedrich, Axel Dahlberg, Elisa Baeumer, Katrin Kroeger, Raphael Lescanne, Brad Mitchell, Lars Kristiansen, Marco Roth, Manish Thapa, Nicolas Brehm, Lea Kraemer, Alvaro Piedrafita, Samuel Gyger, Stefan Tessarini, Arno Bargerbos, Ben-Elias Brandt, Leo Spiegel, Florian Ott, Vilhelm Ryden, Jan-Grimo Sobez, Brennan MacDonald-de Neeve, Robin Eriksson, Ziyad Amodjee, Alex Popert, Youri Popoff.

Please sign up for which preferred quantum-system implementation you would like to give a talk here. Possible topics within this implementation can be found below. If you would like to do your talk on a topic which is not listed below, sign up under "other topics" and add the topic after your name. Please do NOT sign up in groups.

DEADLINE: Tuesday, 17.03.2015.

Sign-Up for final talk

Please remember the following rules for the sign-up and the talks:

1) Every presentation can only be done by a maximum of 3 people. 2 are preferred!
2) Only enter your name into the name field! Do not sign up as two people in the doodle (published later in the semester). Otherwise this might result in overbooking a subject.
3) The "special topic" choice is reserved for the people that suggested that topic. 
4) There are in-lecture presentations, which should be done in the second hour of the main lecture. All the other presentations are held during the exercise class.
5) For each subject an introductory lecture is given by Andreas Wallraff one week before the presentation, except for the Rydberg atoms, which will be on the same day.
6) Please contact your supervisor (indicated in "Topic") at least 2 weeks before your presentation date to set dates for a) discussing the paper and b) practise the talk. 
7) Write a short abstract on your talk (max. 0.5 pages) and send it to (tthiele@phys.ethz.ch) until wednesday before your presentation.

The doodle poll can be found here. FIRST COME, FIRST SERVE!
