CRYOCHIPS pioneers wafer-scale quantum refrigeration technologies, unlocking unprecedented potential of quantum computing. With our Śūnya chips, we enable transformative solutions for scalable, deployable, fault-tolerant quantum systems.
Śūnya is built on quantum tunnel-junction refrigeration. Under optimal bias, energy-selective quasiparticle tunneling extracts heat across superconducting energy gaps in staged, solid-state transitions. Instead of circulating helium mixtures, Śūnya implements discrete solid-state cooling stages: 40K → 4K → mK

Isotope Dependency
Wafer-scale integrated multi-stage cryocoolers with no moving parts. Selective electron filtering by tunnel junctions achieves temperatures from 40K to mK with no fluidics.
Unique conjoint junction design eliminates need for interstage substrates, reducing temperature drops and maximizing coefficient of performance (COP).
Compatible with all quantum computing architectures — superconductive, trapped-ion, neutral atom, and photonic systems. One cooling platform for the entire industry.
Eliminates rare helium isotope dependency entirely. No supply chain constraints, no complex gas handling, no isotope procurement vulnerability.
Collapses >100 m³ dilution refrigerator and 4K chandeliers to <10⁻⁵ m³ wafer-scale chips. 10,000,000 times smaller.
Wafer-scale fabrication scalable to 300 mm wafers. Modular cooling under CQ control—improves coherence and reduces the physical-qubit burden for fault tolerance
Qubit count rises. Control electronics densify. Fabrication advances.
But the cryogenic plant does not scale down.
It's time to drive the cryocooler mammoth extinct!
We partner with quantum system architects to replace dilution refrigerators with solid-state, wafer-scale cooling — from architecture review through validated millikelvin operation.
Align on qubit modality, target temperature range, and physical integration constraints for your architecture.
