Last Friday on April 14th was the World Quantum Day, where the general public had the opportunity to visit Paderborn University and get insight into our optics labs, as well as the cleanroom. Members of our group, along other members of the institute gave tours.
Some more infos about the World Quantum Day can be found in this article on the PhoQS website.
Last week we had our group reflexion meeting. While having breakfast together, we discussed about good scientific practice, future plans and more.
In the evening we met at the Trampoline Park in Paderborn and had a lot of fun. After an hour of jumping around and doing the climbing parcours we were exhausted and filled up our energy with some burgers and fries.
Seven members of our group went to the Spring Meeting of the Atomic, Molecular, Quantum Optics and Photonics Section of the German Physical Society (DPG SAMOP) in Hannover. The conference was held at the Leibniz University from March 5th to March 10th. We presented the following contributions:
Timon Schapeler - Quantum characterization of superconducting detectors (Talk) Johanna Biendl - 3D lithography for single-photon level spectroscopy…
On Tuesday evening most of the group met for our christmas party, we had a great time!
Everyone brought food, we had warm soup and Punsch, cake and more. Together we played a crime game and successfully found the "culprit".
On the occasion of this year's Nobel Prize ceremony, scientists from the University of Paderborn held an evening colloquium last Saturday. Prof. Dr. Tim Bartley, Prof. Dr. Christine Silberhorn and Dr. Benjamin Brecht presented talks for the general public. The event was well attended and many questions were asked, showing the interest of the audience.

Two members of the MQO group went to the Single Photon Workshop (SPW) 2022 in Seoul. The conference took place at the Korea Institute of Science and Technology (KIST) from October 31st to November 4th. We presented the following contributions:
Thomas Hummel – Nanosecond Gating of Superconducting Nanowire Single-Photon Detectors (talk) Nina Amelie Lange – Cryogenic Spontaneous Parametric Down-Conversion (poster)
We enjoyed the conference a…
Three members of the MQO group went to the International Conference on Integrated Quantum Photonics 2022 (ICIQP 2022) in Copenhagen. We presented the following contributions:
Julian Brockmeier – On chip generation and bidirectional electrooptic manipulation of single photons (poster) Maximilian Protte – A Toolbox for Integrated Quantum Photonics Realized by Direct Laser Lithography as a Single Patterning Tool (talk) Frederik Thiele –…
Last Friday the MQO group went for a hike at the Haxtergrund. The weather was not promising at first, however, the rain stopped just before we arrived in the afternoon. Then we could enjoy a nice walk in the autumnal surroundings.
We congratulate Niklas Lamberty who has successfully completed his bachelor thesis titled "Quantum feedforward using electronics at cryogenic temperatures".
End of August we organized a seminar for our group in the mountains of Austria. For a week we stayed in the Ravensburger Hut at almost 2000-meter altitude located close to Langen am Arlberg. We started our trip in Paderborn and in two days we travelled by public transport to Lech am Arlberg. From there it was a three hour walk up to the hut. Even though the weather was not always nice on that day, everyone enjoyed the challenge and the experience…
In our new publication we show the operation of a superconducting single photon detector via a photodiode. Superconducting single photon detectors have become the goldstandard for single photon detection in recent years since they can achieve detection efficiencies of above 95% and show negligible dark noise. These features are vital to realise quantum photonic communication. These superconducting single photon detectors must be operated at…
