CryoLink: Modular cryogenic signal chain for quantum, defence and space
Every module ships with cold S-parameters, heat-load data and calibration records measured at 20 mK.
Make Indian millikelvin measurements indigenous
Build India's first validated cryogenic signal-chain platform — modular hardware that ships with the calibration, heat-load and drift records that make it usable in any cryostat, anywhere.
- 01
Indigenous mK infrastructure
Cryogenic wiring, filtering, thermometry and calibration — designed and validated in India for global quantum labs.
- 02
Validation as a product layer
Every module ships with cold S-parameters, heat-load model, calibration records, drift logs and install SOPs.
- 03
One integrated stack
Harness, RF chain, filters, thermometry and calibration as a single subsystem — retrofit-ready for any cryostat.
Three phases. Seven products. Phase 1 is shipping in 24 months.
Funding from QC LEAP 2026 supports Phase 1 product development end-to-end — three flagship modules with cold-validated datasheets and a pilot installation.
