Hardware-efficient erasure-error detection with an integer fluxonium
Junyoung An, Helin Zhang, Jeffrey M. Gertler +13
The paper demonstrates hardware‑efficient erasure‑error detection and conversion using an integer fluxonium qubit, showing improved state lifetimes and reduced gate errors by detec…
Characterization and Comparison of Energy Relaxation in Fluxonium Qubits
Kate Azar, Lamia Ateshian, Mallika T. Randeria +19
Fluxonium superconducting qubits have demonstrated long coherence times and high single- and two-qubit gate fidelities, making them a favorable building block for superconducting q…
ZZ-Free Two-Transmon CZ Gate Mediated by a Fluxonium Coupler
Junyoung An, Helin Zhang, Qi Ding +19
Eliminating residual ZZ interactions in a two-qubit system is essential for reducing coherent errors during quantum operations. In a superconducting circuit platform, coupling two…
Emergent Harmonics in Josephson Tunnel Junctions Due to Series Inductance
Junghyun Kim, Max Hays, Ilan T. Rosen +11
Josephson tunnel junctions are essential elements of superconducting quantum circuits. The operability of these circuits presumes a -periodic sinusoidal potential of a tunnel…
Non-degenerate noise-resilient superconducting qubit
Max Hays, Junghyun Kim, William D. Oliver
We propose a superconducting qubit based on engineering the first and second harmonics of the Josephson energy and phase relation and . By construct…
