Multi-level π-junction in a proximitized Ge/SiGe quantum dot probed by an on-chip superconducting microwave resonator
Luigi Ruggiero, Vera Jo Weibel, Pauline Drexler +5
Using on-chip microwave measurements, we investigate multilevel -junctions formed by proximitized quantum dot (QD) in a germanium (Ge)/silicon-germanium (SiGe) heterostructure.…

Impact of surface treatments on the transport properties of germanium 2DHGs
Nikunj Sangwan, Eric Jutzi, Christian Olsen +4
Holes in planar germanium (Ge) heterostructures show promise for quantum applications, particularly in superconducting and spin qubits, due to strong spin-orbit interaction, low ef…
