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.…
A coherence sweet spot with enhanced dipolar coupling
Jann H. Ungerer, Alessia Pally, Stefano Bosco +9
Qubits require a compromise between operation speed and coherence. Here, we demonstrate a compromise-free singlet-triplet (ST) qubit, where the qubit couples maximally to the drivi…
Electron quantum optics in graphene
Himadri Chakraborti, Cosimo Gorini, Angelika Knothe +9
In the last decade, graphene has become an exciting platform for electron optical experiments, in many aspects superior to conventional two-dimensional electron gases (2DEGs). A ma…
Photon-mediated long range coupling of two Andreev level qubits
L. Y. Cheung, R. Haller, A. Kononov +9
In a superconducting weak link, the supercurrent is carried by Andreev bound states (ABSs) formed by the phase-coherent reflection of electrons and their time-reversed partners. A…
Charge-sensing of a Ge/Si core/shell nanowire double quantum dot using a high-impedance superconducting resonator
J. H. Ungerer, P. Chevalier Kwon, T. Patlatiuk +6
Spin qubits in germanium are a promising contender for scalable quantum computers. Reading out of the spin and charge configuration of quantum dots formed in Ge/Si core/shell nanow…
Phase-dependent microwave response of a graphene Josephson junction
Roy Haller, Gergő Fülöp, David Indolese +10
Gate-tunable Josephson junctions embedded in a microwave environment provide a promising platform to in-situ engineer and optimize novel superconducting quantum circuits. The key q…
