Key Application Scenarios

Beyond quantum computing, dilution refrigerators provide millikelvin experimental environments for condensed matter physics, materials science, astronomical detector research, semiconductor research, and nanoelectronics.

Quantum Information and Quantum Computing

Superconducting and silicon spin qubits have small energy-level spacings and are sensitive to thermal excitation and environmental noise. A cryogenic environment at approximately 10 mK helps reduce thermal excitation and supports qubit initialization, gate operations, and related low-temperature experiments. The system also provides staged cooling for microwave control chains and cryogenic low-noise amplifiers, supporting low-noise readout of weak quantum signals.

Condensed Matter Physics and Materials Science

Dilution refrigerators can support electrical transport measurements of two-dimensional materials, topological insulators, and heavy-fermion superconductors. Millikelvin temperatures help reduce thermal broadening and lattice-vibration effects. When combined with a high-field magnet system, they provide experimental conditions for studying integer and fractional quantum Hall effects, edge-state transport, and quantum critical phenomena.

Astronomical Observation and Deep-Space Exploration

Dilution refrigerators can support detector development and observation systems for cosmic microwave background, far-infrared, and terahertz astronomy. They provide a stable sub-100 mK operating environment for transition-edge sensors (TESs) and microwave kinetic inductance detectors (MKIDs), supporting high-sensitivity detection of weak radiation signals. Actual performance depends on the detector type and system configuration.

Semiconductor Research and Nanoelectronics

In single-electron transport experiments, thermal energy must be substantially lower than the electrostatic charging energy. Millikelvin temperatures help reduce thermal broadening and provide suitable conditions for studying quantum-dot energy levels, Coulomb-diamond regions, and single-electron pumping, as well as for research in single-electron metrology and nanoelectronic devices.

Four Key Technical and Configuration Features

Low-Vibration and Electrical-Isolation Design

The system uses a pulse-tube cryocooler and can be configured with flexible thermal links. This design maintains thermal conductivity while helping reduce the transmission of mechanical vibration into the cryogenic region and limiting disturbances to sensitive experiments.

Rapid Warm-Up

Selected models include a rapid warm-up function that returns the system from cryogenic temperatures to room temperature under specified operating conditions, reducing waiting time for sample replacement, commissioning, and maintenance. Warm-up time varies by model and configuration.

In-House Developed Cryogenic Temperature Sensors

The system can be equipped with in-house developed cryogenic temperature sensors designed and optimized for dilution-refrigerator environments. These sensors provide stable temperature-monitoring data and support system temperature control and configuration expansion.

Gas-Gap Heat Switch and Pre-Cooling Technology

Selected models use gas-gap heat switches. During the initial cooldown stage, the switch provides a high-conductance thermal path for pre-cooling. At cryogenic operating temperatures, it transitions to a low-conductance state to reduce heat leakage. This technology helps shorten cooldown time and improve operating efficiency.
