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…
Extremely Large Area (88 mm X 88 mm) Superconducting Integrated Circuit (ELASIC)
Rabindra N. Das, Vladimir Bolkhovsky, Alex Wynn +9
Superconducting integrated circuit (SIC) is a promising "beyond-CMOS" device technology enables speed-of-light, nearly lossless communications to advance cryogenic (4 K or lower) c…
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…
