Quantum, A to Z. Built in India, for everyone.
One open place for quantum - papers, patents, companies, people, funding, journals.
A single, public, machine-readable home for everything that matters in quantum technology. Built for school students discovering the field, university and PhD researchers, industry teams scoping pilots, and government and policy stakeholders shaping strategy. All data is released under CC-BY-4.0; the aggregation code is MIT-licensed and maintained by RSL Quantum, which is itself one entry in the registry.
Datasets
Every dataset is available as a single JSON file, served with CORS and a 10-minute edge cache. All under CC-BY-4.0. A Zenodo DOI for the consolidated release is being prepared; until it appears here, please cite this page URL and the dataset access date.
What is being published, by research area
Topic tags are computed by a deterministic keyword classifier shared across the arXiv and Crossref feeds (source). A paper can belong to more than one area. "General" means a quantum paper that did not match any specific subtopic; "unclassified" papers are excluded from the chart below.
Scope
India's National Quantum Mission, approved in 2023, committed approximately USD 730 million over eight years across hardware, software, sensing, communication, and materials. Activity is distributed across academic groups, national laboratories, public sector units, and private companies. There is no consolidated public dataset that lists which Indian companies operate in quantum technology, what they build, and where they are located. This registry is built to fill that gap.
Inclusion criteria are deliberately narrow. A company is added only when its quantum work can be verified against a primary public source. Listed entries include private and public companies that design, build, distribute, or commercially deploy quantum hardware, software, sensors, components, or quantum-adjacent classical tooling. Academic groups and individual researchers are out of scope for the company registry and are surfaced instead through the papers feed.
How to use the data
- Browse the directory at /quantum-india/companies/.
- Download the raw data as JSON or CSV.
- Cite the URL
https://rslquantum.com/quantum-india/with a retrieval date in academic or press use. - Contribute additions or corrections by email to quantum-india@rslquantum.com. Submissions must include a CIN, a primary source link, and a one-line description of the quantum work.
Sources and method
Company entries are drawn from the Ministry of Corporate Affairs
master data, the National Quantum Mission and DST press releases,
DPIIT Startup India recognitions, FITT IIT Delhi incubation
records, and verified press reporting. Each row records the
source used and a verified_via field
naming the specific document, PRID, or certificate reference.
Unverified leads are kept in a separate
candidates_to_verify bucket in the seed file and are
not exposed in the public registry.
The papers feed pulls daily from arXiv category
quant-ph and cross-checks each entry against OpenAlex
for author institutions and country codes. A paper is flagged
India-affiliated when at least one author institution has country
code IN in OpenAlex, or when the title or abstract
names an institution on the canonical list. The canonical
institution list covers the IITs, IISc, TIFR, IISER network, RRI,
HRI, IUCAA, IMSc, IPR, the NIT system, BARC, DRDO, ISRO, JNCASR,
Saha Institute, Bose Institute, Raman Research Institute, and
FITT IIT Delhi.
The aggregator runs once per day at 04:30 UTC and commits its output to a public Git repository, so every refresh is time-stamped and auditable.
