Superconducting qubits are one of the most mature and well-funded technologies for quantum computers. In these systems, the wiring is a vital and costly part, and key for qubit control and readout. Wiring is also a major bottleneck that limits scale-up of the number of superconducting qubits. In this Innosuisse-funded project, carried out together with the Superconducting Quantum Circuits Group from PSI and in collaboration with Huber+Suhner AG, we aim to overcome this obstacle by optimizing wiring hardware and metrics. The goal of this project is to reduce the size of the wiring components and mitigate their adverse effects on the fidelity of operations acting on qubits at large scale.
