Superconducting edge contact to a buried Ge quantum well
Dina Sokolova, Davide Costa, Davide Degli Esposti +4
Semiconductor-superconductor hybrid systems form the basis for a broad range of quantum phenomena, such as Andreev bound states, topological superconductivity, and hybrid quantum H…
Sparse qubit operation in a 66 quantum dot array
Alexader S. Ivlev, Harold L. Co, Damien R. Crielaard +4
Fault-tolerant quantum computation requires increasing the qubit count while maintaining high performance and connectivity. Semiconductor qubits have demonstrated high-fidelity ope…
Gate Dispersive Charge Detection in Ge/SiGe Quantum Dots
M. R. Tanvir, E. Sajadi, M. Veldhorst +2
Spin qubits are an attractive platform for scalable quantum information processing, and recently, laterally gated quantum dots (QDs) in Ge heterostructures have emerged as a leadin…
Probing Residual Noise at a Decoherence Sweet Spot in a Si/SiGe Spin Qubit
Shinwoo Lee, Hanseo Sohn, Jaemin Park +7
In Si/SiGe spin qubits with micromagnets, the longitudinal stray field gradient transduces charge noise into qubit frequency noise and limits coherence. We compare two neigh…
Spectroscopy With Intelligent Feature Tracking for automated characterization of excited-state structure in semiconductor quantum dot devices
A. R. Huffman, Daniel Schug, Merritt Losert +6
The characterization of excited-state structure in semiconductor quantum dot (QD) devices is an important component of tuning them for spin-qubit operation. We present Spectroscopy…
Light-Hole Spin Qubits in Strained SiGe Lattice-Matched to Ge
Edmondo Valvo, Davide Costa, Patrick Del Vecchio +3
Strained germanium (-Ge) quantum wells on metamorphic SiGe buffers have enabled advanced hole-based spin qubit devices. Alternatively, unstrained Ge with lattice-match…
