Source Data — A Cascaded Random Access Quantum Memory (arXiv:2503.13953)

This repository contains the statistical source data and plotting scripts needed to reproduce the main-text figures of the paper. For every figure panel there is (1) a plain-text/CSV dataset and (2) a self-contained Python script that reads the dataset and regenerates the panel.

Deposit scope (figshare vs GitHub)

The figshare deposit (figshare_upload/) contains only the main-text figure source data (Figs 1–4: panels 1c, 2a, 2b, 2c, 2e, 3b, 3c, 4a, 4c, 4d, 4e, 4f), as open-format CSV/TXT. It deliberately excludes analysis code, supplementary-figure data, and published figure images.

The analysis code, notebooks, and supplementary material live in this GitHub repository and are referenced from the paper's Code Availability statement. Data underlying several supplementary figures depends on raw .h5 measurement files that are not redistributed here.

Suggested statements:

  • Data availability → figshare deposit (main-text source data).
  • Code availability → this GitHub repository.

        Fig 3(c)  random read infidelity vs RAQM size                [done]

        Fig 4(f)  random-read error budget                  [done]

All data panels are reproduced and verified against the published values. Pending only: Fig 2(a) and Fig 2(b) raw time traces (awaiting the source files).

(Schematic / circuit / device panels — 1a,b, 2d, 3a, 4b — contain no statistical data and are not included.)

Style

raqm_style.py defines a shared muted/earthy color theme (cream background; terracotta, teal, slate-blue, gold) used by all plotting scripts — an alternative palette to the one in the published figures. Edit it to restyle every panel at once.

Provenance, methods & notebooks

  • SOURCES.md — per-panel map of repo dataset → slab-drive source file → analysis notebook.
  • analysis/ — the actual fitting/extraction functions (RB fits, gate-fidelity conversion, dual-rail parity populations) used to produce the figure data.
  • notebooks/ — reference copies of the analysis notebooks (as run).

Requirements

python >= 3.9, numpy, pandas, matplotlib, scipy

Usage

cd fig2 && python plot_fig2c.py      # writes fig2c_M1-S{1..7}.pdf/.png

Each script writes a .pdf and .png next to itself. Datasets are CSV with a header row; column meanings are documented at the top of each plotting script and in the per-figure README.md.
