Ultrashort infrared light pulses are the key to a wide range of technological applications. The oscillating infrared light field can excite molecules in a sample to vibrate at specific frequencies, or drive ultrafast electric currents in semiconductors. Physicists from the attoworld team at the Ludwig-Maximilians-Universität München (LMU), the Max Planck Institute of Quantum Optics (MPQ) […]
Topological phase detected in spin chains
In a special arrangement of atomic spins, Max Planck physicists have measured the properties of the so-called Haldane phase in an experiment. To do so, they used a quantum mechanical trick. In some materials, there are phases between which a transition is not possible because they are protected by a certain form of symmetry. Physicists […]
More efficiency for optical quantum gates
Researchers at the Max Planck Institute of Quantum Optics succeeded in massively improving the performance of a component that is crucial to optical quantum systems. Future quantum computers are expected not only to solve particularly tricky computing tasks, but also to be connected to a network for the secure exchange of data. In principle, quantum […]
Many body seminar: ZXH calculus for many-body problems
Richard East (QuEnG):The ZX calculus is a formal diagrammatic language typically used by computer scientists for the analysis and simplification of quantum circuits.
Theory Seminar: Light cone tensor network and time evolution
Miguel Frías (MPQ): The transverse folding is a tensor network method to compute timedependent local observables that can sometimes overcome the limitations ofmatrix product states.
Nathalie Nagl wins Otto Hahn Medal of the Max Planck Society
As part of her doctoral thesis, Nathalie Nagl developed a new generation of highly compact ultrashort pulse lasers in the infrared spectral range, which can be used, for example, to precisely analyze blood samples. This should enable diseases to be detected earlier in the future. The Max Planck Society honours this success with the Otto […]

Antiprotons in superfluid: a new way for sensitive measurements of antimatter
A team of scientists at CERN led by MPQ physicist Masaki Hori has found that a hybrid antimatter-matter atom behaves in an unexpected way when submerged in superfluid helium. The result may open a new way for antimatter to be used to study the properties of condensed matter, or to search for antimatter in cosmic […]
Award-winning quantum random number generator
Party mood in our school laboratory PhotonLab. The German Association of School Labs awarded the team led by Dr Silke Stähler-Schöpf and Linda Qerimi a prize for the “Experiment of the Year”. The LeLa award recognises outstanding achievements by school labs and school lab networks. The school lab entered the competition with its quantum random […]
Johannes Zeiher launches new and independent research group “Quantum Matter Interfaces”
For over a year now, Johannes Zeiher and his research group have been building a new experiment at MPQ dealing with the investigation of quantum matter for its application in digital quantum computer. Recently he was able to acquire 3.3 million euros from the BMBF (German Federal Ministry of Education and Research) with his project […]
