Fluxonium Qubit Relaxation Spectroscopy Data for Paper Regeneration

Data supporting a 2026 paper on non-Markovian relaxation in fluxonium qubits, authored by Zetong Zhuang. The 3.8 MB ZIP archive contains the data necessary to regenerate the plots presented in the associated research. It was last updated in April 2026.

Use Cases

• Analyzing relaxation time (T1) dependencies on qubit frequency or flux bias using spectroscopy data.
• Modeling non-Markovian noise spectra by fitting the provided relaxation rate data across different parameter sweeps.
• Reproducing and validating the published figures on fluxonium qubit coherence and environmental coupling.
• Benchmarking theoretical models of qubit-environment interaction against experimental relaxation measurements.

Strengths

• Data is directly tied to a peer-reviewed publication, ensuring scientific relevance.
• The 3.8 MB size indicates a focused dataset suitable for detailed analysis of specific phenomena.
• Published under a permissive CC-BY-4.0 license, allowing for reuse with attribution.

Limitations

• The small 3.8 MB scale suggests limited scope, likely containing only the specific data points for the paper's plots.
• Unknown row and column counts prevent assessment of dataset breadth and feature diversity.
• Lack of documented column names or data structure requires users to infer context from the associated paper.
