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…

Cosmic-ray-induced correlated errors in superconducting qubit array
Xuegang Li, Junhua Wang, Yao-Yao Jiang +15
Correlated errors may devastate quantum error corrections that are necessary for the realization of fault-tolerant quantum computation. Recent experiments with superconducting qubi…

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.…
