About
A thin quantum supplier directory
SourceQuanta is a marketplace for quantum hardware, starting as a directory. The useful unit is the product page: a named part, the company behind it, and public specs. Wave-0 is free discovery. A quote opens the supplier site.
Wave-0 follows a simple lesson from component directories: ship a seeded catalog before the rest of the marketplace. The seed is public web data. The first wedge, gathered on 26 September 2026, is cryogenic RF interconnects and filters in Microwave & RF. On 29 September 2026 the seed also added YQuantum (BiasTs, filters, sample boxes, and a cold finger), Basel Precision Instruments (DACs, preamps, and microwave filter/thermalizers), and qprobe (cryogenic probe stations and accessories). Dilution refrigerators, cryocoolers, and qubit chips are still outside this seed.
Listings use listing_status: published and source: public_seed. Nobody has claimed them. Specs can be incomplete. Where a source was uncertain, the research notes in docs/SOURCES.md say so. There is no price list.
In this version
