The superconducting qubit architecture is one of the leading candidates to realize general-purpose quantum computing. Fraunhofer EMFT aims to achieve scalability of superconducting qubits beyond 1000 qubits by developing foundry-like fabrication processes at 200 mm wafer scale. Currently, we achieve the highest published energy relaxation times of up tp 200 µs for superconducting qubits fabricated on large wafers using industry-standard methods.
The focus of the fabrication processes development is on optimizing both precision and reproducibility in chip production so that these can be applied to build general quantum computers.
