Preprint radar
Recent quantum physics preprints from arXiv (quant-ph) with at least one European organisation on the portal, grouped by technology family. Affiliations come from OpenAlex and are matched to portal organisations through their ROR IDs. Organisations only: no researcher is named. Preprints are not peer reviewed.
Last read from arXiv: 1 Nov 2026, covering submissions up to 29 Oct 2026.
This view holds preprints submitted from 2026-10-16 to 2026-10-29 (252 in the window). arXiv is read daily, two days after submission, and a preprint is listed once OpenAlex has recorded its institutions, so the newest days fill in over time.

Method, sources and limits
- Source: the arXiv API, new quant-ph submissions read daily, two days after submission (one request every 3.5 seconds; metadata CC0 1.0), and OpenAlex works found by the arXiv DOI (CC0 1.0), fifty per request within a small daily budget. A preprint without institutions yet is looked up again daily for its first week, then every three days for 30 days.
- An organisation is European when OpenAlex places it in the EU, EFTA, the United Kingdom or a country associated to Horizon Europe, and it is shown when its ROR ID matches a portal organisation.
- Technology families come from the OpenAlex topics through a curated mapping to the shared taxonomy (checked 2026-10-25); a pillar is narrowed to one family only when the taxonomy keyword rules find exactly one family of it in the title and abstract. Preprints without a mapped topic are shown as "Other quantum".
- Order: the number of European portal organisations (up to five), then the newest. Nothing is ranked by impact, citations or venue.
- Stored: the arXiv identifier, title, a short abstract for 45 days, categories, submission date, DOI and journal reference (left out when it names an author), and the organisations, topics and funders OpenAlex records. No author name is stored or shown.
