Mitigating Capacitive Loading Enables Fast Two-Qubit Gates in Highly Connected Fluxonium Quantum Processors
Quan Guan, Guo Xuan Chan, Xu Dou +2
Fluxonium qubits combine long coherence times with strong anharmonicity, making them attractive for scalable superconducting quantum processors. Recent experiments have demonstrate…
Unified Flux Control Architecture for Fluxonium Qubits
Xianchuang Pan, Jiahui Wang, Tao Zhou +14
Control architectures that reduce hardware overhead while maintaining high-fidelity operations are essential for the continued scaling of superconducting quantum processors. Here w…
Scalable Fluxonium Quantum Processors via Tunable-Coupler Architecture
Ze Zhan, Zishuo Li, Fei Wang +24
Superconducting quantum processors have largely converged on transmon-based architectures, while alternative qubit modalities with intrinsic error protection have lacked a demonstr…
Converting qubit relaxation into erasures with a single fluxonium
Chenlu Liu, Yulong Li, Jiahui Wang +9
Qubits that experience predominantly erasure errors offer distinct advantages for fault-tolerant operation. Indeed, dual-rail encoded erasure qubits in superconducting cavities and…
