We propose alternative approaches to superconducting qubit technology, introducing qubit designs capable of eliminating the need for flux lines. One innovation track will implement SIsFS junctions in a transmon geometry—ferrotransmons. The other will hybridize gatemons and π-junction to deliver a ferrogatemon.
The Physics Department of the University of Napoli has a long- standing tradition on weak superconductivity and superconducting electronics, in particular on the Josephson effect and macroscopic quantum phenomena also in unconventional systems, where know-how on material science combines with deep knowledge on how to engineer quantum coherence in real devices.

QBLOX bv is a Delft-based SME that provides modular and highly integrated control electronics and software for quantum technology. QBLOX was founded in 2018 as a spin-out from QuTech, one of Europe’s leading quantum technology hubs. Since then, the company has grown to 80+ scientists, engineers and developers with backgrounds in electrical engineering, software engineering and physics. QBLOX has focused so far on revolutionizing control stacks for gate model quantum computing by 1) making fully-integrated and extremely scalable hardware that drastically simplifies experimental setups, 2) paving the way towards Quantum Error Correction protocols with 100s of qubits by creating a distributed processor architecture 3) pushing two- qubit gate fidelities by creating electronics with the market’s best noise and drift performance.
