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…
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…
