Flux-noise-resilient transmon qubit via a doubly-connected gradiometric design
J. B. Fu, Da-Wei Wang, B. Ren +12
Frequency-tunable superconducting transmon qubits are a cornerstone of scalable quantum processors, yet their performance is often degraded by sensitivity to low-frequency flux noi…
Efficient Preparation of Decoherence Free Subspace Basis States
Zi-Ming Li, Yu-xi Liu
Decoherence-free subspace (DFS) provides a crucial mechanism for passive error mitigation in quantum computation by encoding information within symmetry-protected subspaces of the…
Speedup Chip Yield Analysis by Improved Quantum Bayesian Inference
Zi-Ming Li, Zeji Li, Tie-Fu Li +1
