QuBE/Qubex: an integrated hardware-software system for superconducting qubit experiments with broadband control
Akinori Machino, Kazuhisa Ogawa, Takefumi Miyoshi +21
Achieving high-fidelity operation in large-scale superconducting qubit systems requires not only control hardware with broad frequency coverage, low crosstalk, and tight synchroniz…

Systematic frequency-collision analysis of the cross-resonance gate outside the straddling regime
Shinichi Inoue, Shotaro Shirai, Shuhei Tamate +4
Frequency crowding remains a major obstacle to scaling fixed-frequency transmon processors. Among the widely used all-microwave two-qubit gates, the cross-resonance (CR) gate is pa…

NbTiN Nanowire Resonators for Spin-Photon Coupling on Solid Neon
Y. Tian, I. Grytsenko, A. Jennings +9
Electrons floating on a solid neon exhibit long charge coherence times, making them attractive for hybrid quantum systems. When combined with high-quality, high-impedance supercond…
