High Impedance Granular Aluminum Ring Resonators
Mahya Khorramshahi, Martin Spiecker, Patrick Paluch +10
Superconducting inductors with impedance surpassing the resistance quantum, i.e., superinductors, are important for quantum technologies because they enable the development of prot…
The spatial correlation of radiation-induced errors in superconducting devices decays over a millimeter
Francesco Valenti, Anil Murani, Patrick Paluch +7
We perform nanosecond-resolution multiplexed readout on six same-chip superconducting microwave resonators. This allows us to pinpoint the impact positions of ionizing radiation on…
Simultaneous sweet-spot locking of gradiometric fluxonium qubits
Denis Bénâtre, Mathieu Féchant, Nicolas Zapata +4
Efforts to scale up superconducting processors that employ flux-qubits face numerous challenges, among which is the crosstalk created by neighboring flux lines, which are necessary…
High quality superconducting tantalum resonators with beta phase defects
Ritika Dhundhwal, Haoran Duan, Lucas Brauch +16
For practical superconducting quantum processors, orders of magnitude improvement in coherence is required, motivating efforts to optimize hardware design and explore new materials…
Low crosstalk modular flip-chip architecture for coupled superconducting qubits
Soeren Ihssen, Simon Geisert, Gabriel Jauma +10
We present a flip-chip architecture for an array of coupled superconducting qubits, in which circuit components reside inside individual microwave enclosures. In contrast to other…
Magnetic bound states embedded in tantalum superconducting thin films
Soroush Arabi, Qili Li, Ritika Dhundhwal +4
In the fabrication of superconducting devices, both in situ and ex situ processes are utilized, making the removal of unwanted oxide layers and impurities under vacuum conditions c…
