Revolutionary breakthrough overcomes longstanding limitations in cryogenic technology, enabling continuous, reliable operation with high cooling power for quantum experiments in the 0.5 K range.
EDMONTON, AB, March 13, 2025 - Zero Point Cryogenics, a leading innovator in ultra-low temperature systems, is proud to announce the launch of its patent–pending Phase Separation Refrigerator—a 500 mK Continuous Cold Cryostat that sets a new industry standard by enabling quantum experiments and quantum technologies to be operated continuously in the 0.5 K range. Until now, the scientific community has been limited by the lack of an affordable, high cooling power, fast, and continuous refrigeration solution at these critical temperatures.
A New Era in Cryogenic Innovation
For decades, researchers have strived to push the boundaries of quantum technology. However, the absence of a practical, continuous refrigeration system operating at 500 mK has constrained the development of next-generation quantum experiments and devices. Zero Point Cryogenics has overcome this barrier by leveraging "phase separation" in a novel way. The system achieves continuous cooling at 500 mK with unprecedented reliability and efficiency—dramatically reducing complexity and reliance on scarce resources such as ³He.
"Our Phase Separation Refrigerator is an entirely new type of cryogenic system," said Dr. John P. Davis, Chief Technology Officer at Zero Point Cryogenics. "While lower and higher temperature solutions have existed, until now, the 0.5 K temperature range has been difficult when needing high-cooling power or continuous operation. This has limited experiments to cryogenic systems that were not a good match. The Phase Separation Refrigerator provides exceptionally fast cooldown times with simple, continuous operation, and efficient use of helium-3, a critical resource."
Unlocking Quantum Potential
The Phase Separation Refrigerator is specifically engineered to meet the unique demands of quantum computing, quantum sensing, and photonic quantum technologies. Its continuous operation at 500 mK makes it an indispensable tool for:
- Quantum Computing and Quantum Devices: By providing a stable, low-temperature environment, the cryostat provides an affordable platform for testing and integrating superconducting qubits and quantum control electronics, allowing for faster prototyping and more reliable experimental outcomes.
- Quantum Sensors and
