Probing the memory of a superconducting qubit environment
Nicolas Gosling, Denis Bénâtre, Nicolas Zapata +8
Achieving fault tolerance with superconducting quantum processors requires qubits to operate within the regime of threshold theorems based on the Born-Markov approximation. This ap…
Liquid metal printing for superconducting circuits
Alexander Kreiner, Navid Hussain, Ritika Dhundhwal +10
Superconducting circuits are a promising platform for implementing fault-tolerant quantum computers, quantum limited amplifiers, ultra-low power superconducting electronics, and se…
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 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…
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…
