Problem
Researchers and engineers working with quantum devices need reliable cryogenic environments at millikelvin temperatures, but traditional cryostats are large, slow to cool, and require complex integration, limiting experimental throughput and flexibility in laboratory layouts.
Solution
Qinu offers compact, fast, and efficient cryostats that reach a base temperature of 200 mK with a 24‑hour cooldown cycle. The system is built from three independently positionable modules—the cryostat, gas‑handling system (GHS), and cryocooler unit (CCU)—allowing flexible placement and easy integration into any lab space. A GM‑type cryocooler provides cooling power down to 4 K, while a custom helium‑4 pipeline forms a closed circuit that can remain cold during sample exchange. The integrated web‑based control software runs on an industrial PC, enabling one‑click cooldown and warm‑up, automated trap cleaning, and remote operation via Ethernet without driver installation. Vibration and acoustic noise are minimized by allowing noisy components to be isolated in separate rooms or sound‑proof enclosures.
Target Audience
Primary customers are research laboratories, university groups, and industrial R&D facilities developing quantum computing, superconducting detectors, and other cryogenic experiments that require millikelvin temperatures with flexible, low‑vibration setups.
