Recently, under the authorization and guidance of the Institute of Quantum Information and Quantum Technology Innovation, Chinese Academy of Sciences (hereinafter referred to as the Quantum Innovation Institute), QuantumCTek Co., Ltd. has completed the engineering‑oriented development and rolled out the first unit of the ez‑Q F1500 dilution refrigerator.
Delivering a cooling power of 1 700 microwatts (μW) at 100 millikelvins (mK) and 48 μW at 20 mK, the ez‑Q F1500 achieves internationally leading single‑core cooling performance. Deliveries of the product will commence in the second half of this year, laying a foundation for China’s subsequent development of kilobit‑scale error‑corrected superconducting quantum computers.
Superconducting quantum computing chips are extremely sensitive to environmental disturbances. Faint thermal noise, electromagnetic waves or mechanical vibrations may trigger quantum‑state decoherence and give rise to computational errors. Therefore, chips must operate in an ultra‑low‑temperature environment close to absolute zero to minimize external interference with quantum states.
As critical hardware that generates ultra‑cold conditions, dilution refrigerators not only provide the thermal environment required for chip operation but also shield nearly all electromagnetic interference and vibration, creating an exceptionally quiet “thinking space” for this “super‑brain”. Without dilution refrigerators, the formidable potential of superconducting quantum computing can hardly be unlocked.
Most mainstream international single‑core models deliver 400‑800 μW cooling power. To meet kilobit‑level requirements, a makeshift solution using two parallel core units has been adopted. Capable of 1 700 μW at 100 mK and 48 μW at 20 mK, the ez‑Q F1500 fulfils kilobit‑chip demands with a single core. It simplifies system architecture while enhancing the refrigerator’s long‑term reliability.
