Who did the looking?

Counted cryptanalysis by author, field and period: the few who wrote the most, and the many who wrote one paper

This is a very early work in progress, and errors are still being addressed. Each counted paper gives its authors equal shares of its class weight, after counting each work once (a preprint of a counted paper adds nothing; a journal extension adds one third). These paper credits add up to the paper counts on the summary page. The papers view instead gives every author the paper's whole class weight. The quantum filter keeps only papers whose main point is a quantum algorithm or a quantum resource estimate; non-quantum keeps the rest. Every figure, ranking and profile follows the filter. Both measure published output only. They do not measure time spent, the importance of a paper, or work that was never published.

Identities have not been checked by a person. Authors were matched to DBLP person records where possible. Name strings that differ from exactly one DBLP person only in dashes, name order or a homonym number are merged into that person here. The remaining unmatched strings (marked †) stay separate, and a failed match can still split one person into two or merge two people into one. To limit the effect of these errors on individuals, two kinds of identity are never named or ranked here: people with fewer than 3 counted papers, and 12 identities on ambiguous names. The second group is common Chinese names where DBLP has not yet assigned papers to a specific person (its unnumbered “disambiguation” profiles and very large catch-all profiles), or where we matched only the spelling. Both groups still count toward totals, contributor counts and the “everyone else” row. Each profile says how many of its papers were matched to the person by name alone. 2026 is a partial year. If you see a paper credited to the wrong person, please open an issue.

Papers by year
Papers per year in the selected field, counted as paper credit (fractional where a paper addresses more than one assumption). Drag across the chart to choose a period; the rankings, figures and numbers below use only papers from that period.
Top 30 contributors, year by year
The most productive named people in the selected period. Each row is one person and each cell one year; darker cells mean more output. Years outside the period are faded, so you can see what each person did before and after it. The bar at the right is the person's total in the period. By period orders rows by the average year of each person's work in this field, which shows one generation handing over to the next. The last row combines everyone else, including people with too few papers to be named, and uses its own shading scale. Click a name for that person's profile.
Who works with whom
The same top contributors as the figure above (choose top 15, 30 or 60 there). A line joins two people who co-wrote a paper in this field during the period, thicker for more shared papers; circle area is the person's paper credit in the period. A group is everyone connected by a chain of co-authored papers in this field and period, including people not named here, so two people can share a group without a direct line. Filled circles in the field colour belong to the period's largest group; open circles had no co-author in this field and period. Hover to see a person's links; click to open their profile.
How concentrated is the field?
Share of each five-year window's paper credit held by its 10 largest contributors, the next 40, and everyone else, plotted at the window's middle year. Each window is ranked separately, so the people in the top 10 change over time. Uses paper credit in both views, and includes people who are not named on this page. Years whose window has less than three papers' credit are omitted; the last two years have shorter windows.
How connected is each field?
Co-author groups in each five-year window, plotted at its middle year, for every field (the selected field is drawn heavier). Effective groups is 1 / ∑ si2, where si is group i's share of the window's paper credit: ten equal groups give 10, and one group holding everything gives 1. Largest group is the share of paper credit held by the best-connected group. Both count only co-authorship on papers in the field and window, so a single paper with many authors can join two groups; read single-year jumps with care. Windows with fewer than eight papers are omitted. The last point is the window 2022–2026, which includes the partial year 2026.
