Quantum Cryogenics Supplier Directory

A supplier directory for quantum cryogenics: dilution refrigerators, cryostats, cryogenic cables, RF components, amplifiers, sensors, vacuum systems, and lab services.

Quantum Cryogenics Supplier Directory

The QCRY supplier directory is a structured map of companies that support the cold infrastructure behind quantum technology. It covers complete cryogenic platforms, component suppliers, measurement infrastructure, low-noise electronics, detector systems, services, and system integrators. The searchable directory and supplier submission queue are below the editorial notes on this page.

This page is not a pay-to-play ranking. It is an editorial directory built from public sources, with supplier-submitted updates reviewed before publication. The goal is to make the market searchable and comparable while keeping technical categories clear.

Profile standards

Each supplier profile should answer:

  • What does the company make?
  • Which cryogenic temperature regimes does it serve?
  • Which quantum use cases are relevant?
  • What specifications are public?
  • Are the products component-level, subsystem-level, or full-system?
  • What related QCRY pages explain the category?
  • When was the profile last reviewed?

How QCRY avoids directory clutter

The directory should not become a spreadsheet of names. Every category needs explanatory context so readers understand why a supplier matters. A dilution refrigerator vendor, a cryogenic cable supplier, and an SNSPD system vendor belong in the same directory because they all support quantum cryogenics, but their buyer questions are different.

Submit or update a profile

Suppliers should provide factual product categories, public links, specification sheets, relevant temperature ranges, quantum use cases, and contact information. Sponsored or supplier-submitted material should be labeled clearly. QCRY editorial pages separate verified public specifications from marketing claims. Use the submission form below to nominate a company or request an update.
