The Max Planck Semiconductor Laboratory (HLL), the Technical University of Munich (TUM), and the Walther Meißner Institute (WMI) of the Bavarian Academy of Sciences (BAdW) have agreed on a groundbreaking collaboration for the joint development of superconducting quantum bits, or qubits, and quantum processors based on them. This partnership, established within the Munich Quantum Valley (MQV), marks a significant step in the research and advancement of quantum technologies. The collaboration aims to develop superconducting qubits as key components for future quantum computers.

Press Release (German)

In their experiment, researchers at the WMI design and characterize a multimode superconducting quantum circuit that forms an artificial molecule. The circuit has two characteristic nonlinear oscillation modes. One is used as a protected qubit mode that can be efficiently decoupled from the measurement circuit to prevent the loss of quantum information. The second mode is used as a mediator that controls the interaction between the qubit mode and the measurement circuit. This protected multimode qubit has the potential to also suppress unwanted interactions between neighboring qubits, thereby solving another major challenge in scaling up quantum processors. It can thus serve as a building block for a quantum processor architecture that retains the performance of a single qubit at large scale.
