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…
Distinguishing types of correlated errors in superconducting qubits
Hannah P. Binney, H. Douglas Pinckney, Kate Azar +15
Errors in superconducting qubits that are correlated in time and space can pose problems for quantum error correction codes. Radiation from cosmic and terrestrial sources can incre…
Driven-dissipative entanglement of distant giant atoms
Aziza Almanakly, Ariadna Soro, Alejandro Vivas-Viaña +15
Quantum interconnects distribute entanglement via controlled light-matter interactions for quantum computing and sensing applications. Many entanglement generation schemes use cohe…
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…
Characterization of Radiation-Induced Errors in Superconducting Qubits Protected with Various Gap-Engineering Strategies
H. Douglas Pinckney, Thomas McJunkin, Alan W. Hunt +26
Impacts from high-energy particles cause correlated errors in superconducting qubits by increasing the quasiparticle density in the vicinity of the Josephson junctions (JJs). Such…
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…
