Construction of the new QCT lab completed

Dilution refrigerator installed

We are pleased to announce that the constructions for the new Quantum Computing Lab (QCL) have been completed! After a preliminary phase of planning, a longer than expected phase of construction took place (thanks to Covid19), not missing hands-on work efforts by ourselves. The entire interior of the QCL has been renovated and rebuild to meet our demands and specifications. Andy designed a partition wall for thermal insulation demonstrating Norwegian rigidity and durability. Further work included the installation of a dedicated earth ground and an isolation transformer to decouple our power grid from unwanted noise. Lastly, a water chiller and related piping were installed to provide for sufficient cooling power for the dilution refrigerator, the most important and technically advanced equipment of the QCL.

Then, with joint forces the dilution refrigerator itslef was installed during the last week of September. We are now proud owner and operator of a BlueFors SD-250 dilution refrigerator, whose base temperature of 19 mK was approved during the initial cooldown. Below are some pictures of the last weeks:
