About

This project, inspired by csrankings.org, is meant as a simple, transparent explorer for publication activity in quantum computing and quantum information. It aggregates papers from a select list of journals and conferences using the OpenAlex API.

The idea is to give a rough sense of where quantum-related papers are showing up, using a select list of venues and a simple aggregation over authors and institutions. It’s a way to poke at the data, not a ranking of research quality.

Methodology and Sources

All of the data you see above comes from querying the OpenAlex API for works whose primary source is each venue, over the chosen year range. For TCS conferences/symposia, we first find paper titles or DOIs from DBLP before querying OpenAlex. For all other venues, querying OpenAlex alone seems to be sufficient. Papers from generic, non-quantum venues are then only kept should they contain one or more keywords from a list of quantum-related words, which can be found in the Github repository for this site. Using the OpenAlex data, we are then able to calculate the total number of publications, "distinct" researchers, and a publications-per-researcher ratio. The tables above are just these aggregates, sorted according to the selected metric. No additional fancy weighting or scoring is occurring behind the scenes. Unfortunately, we are only able to list the 500 institutions with the greatest number of publications before the site begins to slow down.

Everything is driven automatically by the scripts in the associated repository, and there is no hand-tuning of individual author lists or affiliations.

Limitations and caveats

There is a great deal of room for improvement here. In particular:

  • Coverage is incomplete. Not all venues are included, and even for included venues, some years or papers are missing from OpenAlex. TCS-style quantum work is especially easy to miss if the title looks “classical”.
  • Name disambiguation is imperfect. Different people with similar names can get merged; the same person can appear multiple times if their records are split. You will see duplicate entries for some researchers and institutions.
  • Affiliations move around. People change institutions, list multiple affiliations, or have incomplete affiliation data. Here, a paper is counted for an institution if at least one author is listed with that affiliation in the metadata.
  • The venue list and keyword filter are opinionated. They reflect my attempt to capture a decent chunk of quantum work, not a complete picture of the field. As a rule of thumb, you should uncheck any venues not associated with your subfield (e.g. if you're interested in theoretical quantum cryptography, PRL/A/X and others should be unchecked). Failing to do so will lead to an unnecessary number of false positives. False negatives are also incredibly common, and as such, using the venue filter is far more reliable than the subfield one.
  • Numbers are noisy. Small changes in venue choices, keyword lists, or affiliation grouping can move institutions up or down quite a bit.

Disclaimer

The dataset is automatically generated from public metadata and does not reflect any qualitative judgment about researchers or institutions. The ordering above is simply the result of sorting by the chosen metric (e.g., total publications) and should not be interpreted as an official ranking.

The tool is in active development, the scripts may change, and the numbers will move as OpenAlex updates its records. There are almost certainly bugs. If something looks wrong, or if you’d like to suggest a venue or improvement, feel free to shoot me an email at the address listed on my homepage.
