Characterization of superconducting through-silicon vias as capacitive elements in quantum circuits
Thomas M. Hazard, Wayne Woods, Danna Rosenberg +13
The large physical size of superconducting qubits and their associated on-chip control structures presents a practical challenge towards building a large-scale quantum computer. In…
Decoherence of a tunable capacitively shunted flux qubit
R. Trappen, X. Dai, M. A. Yurtalan +19
Quantum annealing is a method to solve optimization problems that leverages quantum tunneling in a coupled qubit system. We present a detailed study of the coherence of a tunable c…
Probing entanglement across the energy spectrum of a hard-core Bose-Hubbard lattice
Amir H. Karamlou, Ilan T. Rosen, Sarah E. Muschinske +16
Entanglement and its propagation are central to understanding a multitude of physical properties of quantum systems. Notably, within closed quantum many-body systems, entanglement…
High-Fidelity, Frequency-Flexible Two-Qubit Fluxonium Gates with a Transmon Coupler
Leon Ding, Max Hays, Youngkyu Sung +16
We propose and demonstrate an architecture for fluxonium-fluxonium two-qubit gates mediated by transmon couplers (FTF, for fluxonium-transmon-fluxonium). Relative to architectures…
Learning-based Calibration of Flux Crosstalk in Transmon Qubit Arrays
Cora N. Barrett, Amir H. Karamlou, Sarah E. Muschinske +13
Superconducting quantum processors comprising flux-tunable data and coupler qubits are a promising platform for quantum computation. However, magnetic flux crosstalk between the fl…
Evolution of Flux Noise in Superconducting Qubits with Weak Magnetic Fields
David A. Rower, Lamia Ateshian, Lauren H. Li +18
The microscopic origin of magnetic flux noise in superconducting circuits has remained an open question for several decades despite extensive experimental and theoretical inv…
