Ordinary computers fear heat — a spinning fan solves it. Superconducting quantum chips are the opposite: qubits must be frozen to near absolute zero before they quiet down. The chip alone is not enough; you also need an ultra-low-temperature refrigerator, measurement and control electronics, cables, and thermometers. On QuantumCTek's official website, under the "Quantum Computing Products" section, the company mainly sells exactly these supporting components, along with full-system solution capability.
The company's position on this line
According to the official company profile: QuantumCTek is the sole unit that participated in developing the "Zuchongzhi" series of superconducting quantum computers, helping refresh superconducting "quantum computational advantage" records. It has launched core components such as measurement-control systems and dilution refrigerators, and describes itself as one of the few companies worldwide able to provide high-performance full-stack superconducting quantum computing solutions. Specific chip qubit counts and algorithm details should follow public materials from the research side; this article only covers products and capabilities stated on the official website.
Ultra-low-temperature platform: freezing the chip
Dilution refrigerators provide superconducting chips an environment near absolute zero. The official product list includes:
- Ultra-low-temperature, ultra-low-noise platform: main body includes the refrigerator, vibration damping, magnetic shielding, water cooling, and signal transmission; QuantumCTek dilution refrigerators can provide environments down to 10mK.
- ez-Q F500: aimed at superconducting quantum computing with up to a hundred qubits. Official specs (product page): no-load temperature ≤10mK, cooling power at 20mK ≥14μW, cooling power at 100mK ≥500μW, cooldown time ≤30h, sample space diameter × depth 320mm × 350mm. Optional magnets, fast sample-exchange insertion rods, and optical windows are available.
- ez-Q F1100: self-developed single-core design for kilo-qubit-scale systems; the site says it can be losslessly upgraded to the Fridge1500 with about 50% performance improvement.
- ez-Q F1500: also targeting kilo-qubit systems, with claimed ~50% higher cooling power than comparable models. Specs: no-load temperature ≤8mK, cooling power at 20mK ≥42μW, at 100mK ≥1500μW, sample space 590mm × 516mm, 6 side-loading ports for measurement-control installation.
- Superconducting quantum computing cryogenic cable assemblies: customized RF components and cabling solutions by application
- Ruthenium oxide thermometers: per the site, mainly for the 6mK–200mK range, covering the extreme low temperatures required for quantum computing
- QuantumCTek dry cryotrap CT-D: continuously purifies circulating helium gas, enabling long unattended operation with dilution refrigerators
- Ultra-low-temperature controller TC16: integrates scanning and temperature control, with desktop control software
Who buys these? Quantum computing labs, condensed-matter physics, nanomaterials, astronomical observation, and other teams needing extreme cryogenics — the website lists these as typical applications.
Measurement and control: telling the qubits "how to move"
Once the chip is frozen, microwave and other signals must perform logic-gate operations. The official ez-Q® Engine superconducting quantum measurement and control system, developed by QuantumCTek jointly with the University of Science and Technology of China (USTC), targets multi-qubit superconducting needs; a single unit integrates control resources for up to 8 qubit-drive and 2 readout channels, and the site states it helped "Zuchongzhi 2.0" demonstrate quantum computational advantage.
A 2025 official news item, "Kilo-qubit superconducting quantum measurement and control system completes shipment," further introduces ez-Q® Engine 2.0: designed for kilo-qubit scale; a single chassis supports up to 128 data qubits and 256 coupling qubits, and 8 units can complete kilo-qubit control tasks; integration density improved over 10× versus the previous generation; it is stated to be supporting development of "Zuchongzhi 3.0," with stability and precision validated on "Tianyan 504"; and it will provide measurement-control services totaling more than 5,000 qubits for multiple institutions. These figures are per that news page.

The takeaway
Reading QuantumCTek's quantum computing product page is like looking at the "utilities" of a superconducting quantum computer: the fridge (dilution refrigeration), the command console (measurement and control), plus cables and thermometers. To verify model numbers and cooling power, just check the official F500/F1500 product pages and the Engine news page.
