Christ­mas mar­ket & Eis­stockschießen

Last Friday we had our "Group Reflection Meeting". At this meeting, which we organize twice a year, we discuss topics that are important to us as a group. This time it was about equality in physics, scientific writing and working with superconducting detectors. After our meeting, we met at the Christmas market in Paderborn to eat something and drink Glühwein. Afterwards, we went Eisstockschießen, where we played against each other in two teams…

BMBF status meet­ing in Han­nov­er

Last week three members of our group joined the BMBF Quantum Futur status meeting in Hannover. All Quantum Futur grant recipients had the chance to present their work and future plans. Prof. Bartley showed our results on cryogenic integrated optoelectronics, including our latest cryogenic feedforward experiment. We also presented a poster on everything our group did on cryogenic frequency conversion and single-photon detectors in the past years…

Group hike at Hax­ter­grund

Last Friday, we enjoyed a sunny afternoon in the Haxtergrund, which is a forest park close to university. Just before the time change, we went on an easy group hike together to make use of one of the last days with longer daylight. The weather was awesome, providing a lot of sunlight and about 20°C for our group event. We all enjoyed the hike and the great view we had on the colorful autumn trees.

New pub­lic­a­tion com­bines quantum op­tics and high-per­form­ance com­put­ing

In our latest publication from Timon Schapeler, we have collaborated with the Paderborn Center for Parallel Computing (PC2) to combine the two fields of experimental quantum optics and high-performance computing for the first time. We provided the experimental data on a large scale quantum detector, capable of detecting one million photons, to characterize it in a quantum mechanically consistent way. Due to the size of the detector (and thus the…
