Mariusz Klimczak<p>A third person take of the poster session at CLEO/Europe 2025 conference in Munich this June. Explaining contents of my poster on second-order optical nonlinear response of epitaxial rhombohedral boron nitride and observed couplings of blue-violet incident light with defects active in the UV-A and UV-C.

Universität Innsbruck<p>Excitons are elementary excitations in solids. A research team at the University of Innsbruck has now devised a method to specifically manipulate dark excitons in semiconductor quantum dots. They have succeeded in controlling these optically inactive quasiparticles and harnessing their unique properties for the storage and processing of quantum states.</p><p>👉 <a href="https://www.uibk.ac.at/en/newsroom/2025/keeping-the-photon-in-the-dark/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">uibk.ac.at/en/newsroom/2025/ke</span><span class="invisible">eping-the-photon-in-the-dark/</span></a></p><p><a href="https://social.uibk.ac.at/tags/quantumphysics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>quantumphysics</span></a> <a href="https://social.uibk.ac.at/tags/quantumdots" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>quantumdots</span></a> <a href="https://social.uibk.ac.at/tags/photonics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>photonics</span></a> <a href="https://social.uibk.ac.at/tags/physics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>physics</span></a> <a href="https://social.uibk.ac.at/tags/excitons" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>excitons</span></a></p>

Continued thread

The research was carried out by Santosh Mutum, Patrick Vliex, Jonas Bühler, Dennis Nielinger, Mario Schlösser, and Stefan van Waasen - all from our institute ICA at @fzj

Thank you to everyone who joined the session and contributed to the discussions. It was a great opportunity to share our progress and connect with the broader quantum technologies community. 2/2

Two new types of photonic computer chips have been developed that match purely electronic chips in their raw performance. The new chips can be integrated with conventional silicon electronics and could find use in energy-hungry technologies such as #AI.

With the ‘MetalnfoLab’, the #AbbeCenter of #Photonics at #UniJena is creating a state-of-the-art laser infrastructure to research nanostructured metasurfaces for information processing. Short-pulse and continuous wave laser systems form the core of the laboratory, which is used on an interdisciplinary basis and promotes strategic research approaches with light.

The European Regional Development Fund (EFRE) is supporting the laboratory with 630,000 euros. Thank you for that! 🙏 🇪🇺
