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…
Global Parametric Gates for Multi-qubit Entanglement
Jize Yang, Lin Guo, Haonan Xiong +8
We propose and experimentally demonstrate a global parametric gate that generates multi-qubit entangled states in a single step. By applying a parametric drive to a common qubit at…
Scalable Low-overhead Superconducting Non-local Coupler with Exponentially Enhanced Connectivity
Haonan Xiong, Jiahui Wang, Juan Song +8
Quantum error correction codes with non-local connections such as quantum low-density parity-check (qLDPC) incur lower overhead and outperform surface codes on large-scale devices.…
