A quantum system consisting of only 51 charged atoms can assume more than two quadrillion different states. Calculating the system's behavior is a piece of cake for a quantum simulator. Yet even with today's supercomputers it is almost impossible to verify the result. A research team from the University of Innsbruck and the Technical University of Munich (TUM) has now shown how these systems can be described using equations from the 18th century.
Ever smaller electronic components, high-precision sensors, tap-proof communication methods or quantum computers that are far superior to conventional computers: At TUM, we are pursuing cutting-edge research in quantum technology. We are creating the basis for technical innovations that will make people’s lives easier in the future through interdisciplinary collaboration of natural and engineering sciences.
Entirely new technologies are made possible by the peculiar rules of quantum mechanics – like, for example, the quantum computer. Kai Müller is professor for Quantum Electronics and Computer Engineering at Technical University of Munich (TUM). Together with a colleague of the Cluster of Excellence „Munich Center for Quantum Science and Technology“ (MCQST) he explains basic quantum phenomena and their applications, such as quantum communications.
Just as electrons flow through an electrical conductor, magnetic excitations can travel through certain materials. Such excitations, known in physics as "magnons" in analogy to the electron, could transport information much more easily than electrical conductors. An international research team has now made an important discovery on the road to such components, which could be highly energy-efficient and considerably smaller.
Quantum technologies, sustainability management and additive manufacturing – the TUM Institute for LifeLong Learning is launching several new part-time certificate programs.
As one of the founding institutions, the Technical University of Munich (TUM) is making crucial contributions to the development of Munich Quantum Valley. The goal is to develop and build quantum computers and to make them available for scientific applications, together with other partners from science and industry in the spirit of a ONE MUNICH strategy and with the help of generous government funding.
While conventional electronics relies on the transport of electrons, components that convey spin information alone may be many times more energy efficient. Physicists at the Technical University of Munich (TUM) and the Max Planck Institute for Solid State Research in Stuttgart have now made an important advance in the development of novel materials for such components. These materials may also be the key to quantum computers that are less susceptible to interference.
While the number of qubits and the stability of quantum states are still limiting current quantum computing devices, there are questions where these processors are already able to leverage their enormous computing power. In collaboration with the Google Quantum AI team scientists from the Technical University of Munich (TUM) and the University of Nottingham used a quantum processor to simulate the ground state of a so-called toric code Hamiltonian – an archetypical model system in modern condensed matter physics, which was originally proposed in the context of quantum error correction.
Diamonds for quantum technology, a test for urinary tract infections and a machine learning method for testing computer games: these three start-ups ideas were announced yesterday as winners of the TUM IDEAward. The day also marked the first-ever presentation of the TUM Deep Tech IDEAward, offered to teams established in other countries that wish to launch their start-up in Munich.
A team at the Technical University of Munich (TUM) has designed and commissioned the production of a computer chip that implements post-quantum cryptography very efficiently. Such chips could provide protection against future hacker attacks using quantum computers. The researchers also incorporated hardware trojans in the chip in order to study methods for detecting this type of “malware from the chip factory”.
The BMW Group will support future research on quantum computers at the Technical University of Munich (TUM). The contract establishing the endowed chair for Quantum Algorithms and Applications ("Quantenalgorithmen und -anwendungen") was signed by TUM president Thomas F. Hofmann, BMW AG Board of Management member Frank Weber and BMW AG CIO Alexander Buresch.
