Low-Noise Quantum Dots in Ultra-Shallow Ge/SiGe Heterostructures for Prototyping Hybrid Semiconducting-Superconducting Devices
M. Borovkov, Y. Schell, D. Sokolova +15
Planar germanium is currently the only semiconducting platform where high-coherence spin qubits and proximity-induced superconductivity have each been demonstrated. Recent research…

Granular aluminum induced superconductivity in germanium for hole spin-based hybrid devices
Giorgio Fabris, Paul Falthansl-Scheinecker, Devashish Shah +19
In superconductor-semiconductor hybrid structures, superconductivity and spin polarization are competing effects as magnetic fields break Cooper pairs. They can be combined using t…

A gate tunable transmon qubit in planar Ge
Oliver Sagi, Alessandro Crippa, Marco Valentini +10
Gate-tunable transmons (gatemons) employing semiconductor Josephson junctions have recently emerged as building blocks for hybrid quantum circuits. In this study, we present a gate…
