Leiden Cryogenics
The Dutch manufacturer builds cryogenic platforms that cool quantum chips and their measurement wiring. Its CF-CS110 range supplies configurable laboratory systems; Quper targets faster chip-testing cycles using a tabletop layout.

Assessment reviewed 11 Sept 2026 · Research reviewed 11 Sept 2026
What it does. Where it fits.
Helium-3/helium-4 dilution refrigeration with customized RF wiring and low-temperature sample access.
Who should look closer
Quantum-chip laboratories selecting a configurable millikelvin platform or exploring faster test turnaround.
QubitWire’s editorial assessment of practical fit.Configured refrigerator systems by enquiry
CF-CS110 systems are offered directly; the Quper page specifies Q4 2026 order acceptance.
Check the current access route ↗What has been demonstrated
IFAE reports a delivered refrigerator entering cooldown. The Quantum Delta NL account describes the separately developed Quper prototype and its OrangeQS Juice controller.
What remains unresolved
Cooling specifications are supplier claims. IFAE reported initial cooldown rather than completed base-temperature acceptance; Quper order acceptance is advertised for Q4 2026, so it is not treated as generally shipping.
The next question to watch
Publish sustained cooling-load and turnaround measurements from customer quantum-device testing.
A research question, not a promised milestone.QubitWire coverage
