what we do
Our field
of research
01
Quantum Systems
We study the fundamental physics of solid-state based quantum systems and advance their fabrication technology to lay the basis for applications in quantum computing, quantum communication, and quantum sensing.
02
Quantum Communication and Sensing
We study the foundations of quantum microwave communication and sensing. We also develop quantum microwave technologies for the realization of quantum local area networks and advanced sensing methods.
03
Quantum Computing and Information Processing
Our mission is to investigate complex quantum systems, engineer novel devices and educate students to advance quantum technologies for scientific and societal impact.
04
Quantum Theory
We develop analytic and numerical methods for modelling the quantum properties of superconducting circuits, nanomechanical devices, spin ensembles and hybrid quantum systems. Our goal is to identify improved protocols for practical quantum communication and quantum information processing applications, but also to explore novel quantum many-body phenomena that arise in such artificial quantum devices with specifically engineered properties and interactions.
05
Magnetism and Spintronics
We study the ordering of spins, magnetization dynamics and spin transport in magnetic materials to understand the formation of complex spin textures, their high-frequency response and the transport of angular momentum. We fabricate complex magnetic heterostructures and nanostructures required for advanced data storage and the next-generation spintronic devices.
06
Superconductivity and Correlated Electron Systems
Superconductivity is one of the most fascinating but also complex and challenging phenomena in solid-state physics. We focus on the fundamental understanding of the mechanism of superconductivity in materials such as the cuprates, iron pnictides or organic metals.

Rudolf Gross receives Werner Heisenberg Medal

Rudolf Gross received the Werner Heisenberg Medal of the Alexander von Humboldt Foundation in recognition of his special services in promoting international scientific cooperation and as a long-standing member of the Selection Committee for the Humboldt and Friedrich Wilhelm Bessel Research Awards. "It was a very fulfilling task to support the AvH Foundation in granting up to 100 awards every year to internationally leading researchers of all disciplines from abroad in recognition of their academic excellence", Rudolf Gross states. "Promoting international coopoeration will becomes even more important today to fill in trenches caused by politics", he adds.

‘Chiral phonons for spintronics' funded by DFG

The German Science foundation (DFG) funds ‘Chiral phonons for spintronics (CHIPS)‘, which is the only physics focused research unit within this funding round. CHIPS wants to understand the physical properties of these chiral phonons in connection with magnetism and spintronics, i.e. in connection with the spin of electrons. How can chiral phonons be generated, transported and recorded? In order to get to the bottom of these questions, the group is looking at time and length scales at the atomic level that have not yet been investigated. This should make it possible to gain new fundamental insights into phonons and potentially identify new spintronic applications. The collaborative effort unites reasearch teams at the University of Konstanz, the University of Augsburg, the Freie Universiät Berlin, the Max-Born-Institut Berlin, the RWTH Aachen, and the Walther-Meißner-Institut.

Rudolf Gross goes into retirement

On April 1st, 2025, Prof. Rudolf Gross retires as Scientific Director of the Walther-Meißner-Institute after shaping the development of the institute for nearly 25 years. During this time, he established WMI as a leading research center in the fields of superconductivity, magnetism, materials science, and quantum technologies, as well as one of the key institutes in the Munich quantum science ecosystem. Today, we celebrate his last official working day with a traditional Weißwurstessen.

Thank you, Rudolf, for everything you have done for the institute!

The toolsets for building quantum computers continue to expand. At WMI, we have leveraged simultaneous parametric interactions to realise Perfect State Transfer between distant superconducting qubits in a chain. Our results reveal that for larger excitation numbers, the phase of the transferred state depends on the number of excitations in the chain. Using this property, we prepare a GHZ state with 88.08% fidelity in a single transfer operation, demonstrating its effectiveness for efficient entanglement generation.

Already in 2010, WMI proposed Planck spectroscopy as an efficient tool for the calibration of cryogenic microwave setups (cf. Mariantoni et al., PRL 105, 133601 (2010)). Now, WMI researchers propose an improved version of Planck spectroscopy, allowing for the in-situ estimation of signal losses in the cryogenic setup used for quantum state tomography of weak microwave signals. With this improved technique they can resolve changes in microwave losses as small as 0.1 dB. Among others, this allows for the more precise characterization of quantum limited amplifiers.

Bavarian State Government supports MQV beyond 2026

The Bavarian state government reaffirmed its strong commitment to Munich Quantum Valley (MQV) by deciding to support this important part of its Hightech Agenda beyond the first funding period ending in 12/2026. This decision will allow MQV to implement its ambitious mission, namely to develop and operate cutting-edge quantum computers for real-world applications in collaboration with visionary start-ups and leading industrial partners. "I am very happy about this this important decision as it will reinforce Bavaria's global position at the forefront of the quantum revolution", Rudolf Gross, the former Scientific and Managing Director of MQV, points out.
