CZS Junior Research Group "Quantum Network Node"
Stephan Welte and his team are building a hardware platform for quantum network nodes based on neutral atoms in optical cavities. The atoms act as stationary quantum memories, linked by flying optical qubits encoded in the polarization of light. Using a model quantum network built on this platform, we will show how we aim to realize a quantum internet architecture in the long term.
Talk: Tuesday, October 6, 9:45 am. Stephan Welte presents "Quantum Networks: Connecting Atoms with Light" (Speaking Zone, 2F17)
CZS Junior Research Group “Quantum Information and Many-Body Physics”
Patrick Emonts and his team will show how to certify quantum devices. Experimental systems are growing beyond what classical computers can simulate, so we need new ways to build trust in their results. By combining device-independent methods such as Bell inequalities with two-sided bounds from variational and relaxation-based computations, we can certify the correctness of quantum computations without solving the system itself.
CZS Junior Research Group “Dynamical Control at the Atomic Scale”
Laëtitia Farinacci and her team investigate how electric fields couple to nanostructures with atomic-scale precision. One project, carried out in collaboration with Jake McGuire (Institute of Physical Chemistry), focuses on spin-electric coupling in dithiolenes. Another explores magnetic bound states in superconductors.
Quantum Effects Academy
The physics education research group at the University Stuttgart is running the school lab „Spiel der Kräfte“. Here, high school students can get in contact with modern science. At Quantum Effects selected experiments will be presented that reach from first principles like interference to complex applications like a NV-based magnetometer that has been developed in a project “QOOOL Sensing”. Also you can test the quantum technology game QUANTista. All experiments are designed so that you can build your own experiment – QT hands on!
The physics didactics team as well as the collaboration partners of the different projects will be ready to answer your questions.
Planned experiments and phenomenae:
- interferometers
- spectroscopy
- fluorescence (QOOOL Kit Fluoro)
- magnetic field measurements (QOOOL Kit Magneto)
- sensing using quantum sensors
- quantum cryptography (BB84-protocol)
- single photon experiments (2QA)
