WACQT Lab course

Welcome to the homepage for the WACQT Rare earth qubit lab.

The lab takes place September 24-26.  The laboratory exercise is made in groups of four. The 24th there will be an introductory lecture and preparations for the lab. The 25th and 26th there will be parallel activities. The 25th some groups will carry out the lab and the other groups will visit labs and research groups in Lund and the 26th the groups will switch.We expect to run one group also the 24th.

Laser safety

To make sure that you have safe routines inside a laser lab you need to watch a laser safety move. For students enrolled at Lund University this is connected with also passing a quiz.

However, for a single occasion as we have here with the WACQT lab we have been allowed to make it a little bit less strict. However you still need to watch the safety movie:


Anyone, including researchers with many years of laser experience need to watch this before working in our labs. If you in general are unfamiliar with lasers you should before looking at the safety video first watch the introductory video:


Before starting the lab here in Lund you will need to sign a document where you assure that you have seen and understood the video(s).

We expect that some of you will carry out the lab already the first day in Lund so it is recommended that you look at the video(s) before arriving in Lund.

Detailed schedule

The program will start at 11.00 24/9 and finish 17.00 26/9.

Detailed schedule


Please read the lab instructions before you come to Lund. It will definitely be helpful for making better use of the introductory lecture and a few of you will also take the lab already the first day and then it is necessary to have read the instructions before, otherwise there is too little time for the lab preparations.


After the lab you need to write a report. In the report you will describe the rare-earth qubit system and the mechanism for qubit-qubit interaction and how this can be used for gate operations. Then there will also be a number of specific questions in the lab instruction that you will need to answer. There will be one report per group.
