What gets listed and what does not

Inclusion criteria

1. Legal entity. The company must be a legally registered entity. For companies incorporated in India, the Ministry of Corporate Affairs CIN is required. For foreign entities with an Indian subsidiary or branch, the Indian entity's CIN is required.
2. Quantum work. The company must design, build, distribute or commercially deploy quantum hardware, quantum software, quantum sensors, quantum communication systems, quantum cryptography systems, or quantum-inspired classical methods marketed as such. Academic research groups without a commercial entity are out of scope.
3. Primary source. One of the following must support the quantum work: an MCA record that states the quantum scope; a National Quantum Mission, DST or PIB release that names the company; a DPIIT Startup India recognition in the quantum sector; a FITT or other recognised incubator record; or a peer-reviewed publication or patent record under the company's name. A company-data website that copies MCA records can support the entity details in criterion 1, but it is not a primary source for this criterion.
4. Active status. The MCA status must be Active or the equivalent. Struck-off, dormant and dissolved entities are not listed.

A company cited solely through a third-party copy of MCA data is not listed until a direct source is added. One listed row does not yet cite a primary source for the quantum work; the companies page marks it.

Out of scope

• Companies whose quantum work is a marketing claim with no verifiable artefact.
• Investment vehicles, trading desks and consulting brands that do not carry out quantum research or build quantum products.
• Individual researchers without a registered company. The publication and researcher datasets cover individuals through their affiliations.
• Companies whose Indian operation is a sales office, with no research, development or engineering work in India.

Re-verification

Every entry carries a last_verified_at date. An entry that has not been checked for more than 90 days is marked "Needs re-verification" on the companies page until it is checked again against MCA records and its cited sources. An entry that no longer meets the criteria is removed from the registry.

How to submit, correct or appeal

Submissions, corrections and removal requests are accepted by email at quantum-india@rslquantum.com. A submission must include the legal name, MCA CIN, registered office, date of incorporation, a one-line description of the quantum work, and a link to the primary source. A correction must name the existing entry and cite the source for the corrected fact. An appeal of a rejection or removal must state which criterion is contested and cite the relevant primary source.
