Low loss superconducting resonators enabled by aluminum microstructural engineering and dielectric trimming
Mahmoud Almansouri, Umar T. F. Alhuwaymel, Ibraheem AlYousef +5
Material losses in superconducting circuits fundamentally limit qubit coherence times and resonator quality factors. Most research efforts focus on mitigating losses at circuit int…
Flux Pumped Kerr-Free Parametric Amplifier
Kagan Yanik, Irwin Huang, Bibek Bhandari +7
We propose a flux-pumped superconducting parametric amplifier based on symmetrically threaded superconducting quantum interference devices (SQUIDs) that achieves a Kerr-free operat…
Quantum Benchmarking of High-Fidelity Noise-Biased Operations on a Detuned-Kerr-Cat Qubit
Bingcheng Qing, Ahmed Hajr, Ke Wang +19
Ubiquitous noises in quantum systems remain a key obstacle to building quantum computers, necessitating the use of quantum error correction codes. Recently, error-correcting codes…
Symmetrically Threaded Superconducting Quantum Interference Devices As Next Generation Kerr-cat Qubits
Bibek Bhandari, Irwin Huang, Ahmed Hajr +7
We theoretically explore an alternative circuit for Kerr-cat qubits based on symmetrically threaded Superconducting Quantum Interference Devices (SQUID). The Symmetrically Threaded…
