Microwave Crosstalk in Planar Superconducting Quantum Devices
Yongxin Song, Dominic Hagmann, Kieran Dalton +5
Microwave crosstalk poses a major challenge to scaling superconducting quantum devices as it introduces excess control errors. Although its magnitude and impact have been explored…
Assessing the Sensitivity of Niobium- and Tantalum-Based Superconducting Qubits to Infrared Radiation
Michael Kerschbaum, Felix Wagner, Uroš Ognjanović +7
The use of tantalum films for superconducting qubits has recently extended qubit coherence times significantly, primarily due to reduced dielectric losses at the metal-air interfac…
Microwave spectroscopy of few-carrier states in bilayer graphene quantum dots
Max J. Ruckriegel, Christoph Adam, Rebecca Bolt +8
Bilayer graphene is a maturing material platform for gate-defined quantum dots that hosts long-lived spin and valley states. Implementing solid-state qubits in bilayer graphene req…
Resource-Efficient Cross-Platform Verification with Modular Superconducting Devices
Kieran Dalton, Johannes Knörzer, Finn Hoehne +7
Large-scale quantum computers are expected to benefit from modular architectures. Validating the capabilities of modular devices requires benchmarking strategies that assess perfor…
Fast Flux-Activated Leakage Reduction for Superconducting Quantum Circuits
Nathan Lacroix, Luca Hofele, Ants Remm +14
Quantum computers will require quantum error correction to reach the low error rates necessary for solving problems that surpass the capabilities of conventional computers. One of…
Development of Nb-GaAs based superconductor semiconductor hybrid platform by combining in-situ dc magnetron sputtering and molecular beam epitaxy
Clemens Todt, Sjoerd Telkamp, Filip Krizek +10
We present Nb thin films deposited in-situ on GaAs by combining molecular beam epitaxy and magnetron sputtering within an ultra-high vacuum cluster. Nb films deposited at varying p…
Calibration of Drive Non-Linearity for Arbitrary-Angle Single-Qubit Gates Using Error Amplification
Stefania Lazăr, Quentin Ficheux, Johannes Herrmann +12
The ability to execute high-fidelity operations is crucial to scaling up quantum devices to large numbers of qubits. However, signal distortions originating from non-linear compone…
