Leiden Cryogenics partners with OrangeQS for compact dilution refrigerator development

The Quper compact dilution refrigerator can cool samples below 25 millikelvin and return to room temperature in less than 24 hours. It does not require liquid nitrogen and uses significantly less helium-3 than traditional cryostats. The project took three years from conception to prototype. The fridge offers remote monitoring via OrangeQS’ open-source operating system, OrangeQS Juice, and SubZero cryogenic control software. The development addresses a customer request for fast, compact, simple, but fully functional dilution refrigerators for applications like quantum chip testing and development, optical or beamline experiments. Traditional cryostats can take more than 24 hours to warm up and cool down, slowing R&D efforts. Quotes: "Fridge can cool samples below 25 millikelvin", "tabletop system has an inverted fridge design and can cool samples below 25 millikelvin before returning to room temperature in less than 24 hours.", "without the need for liquid nitrogen and with a significantly lower helium-3 requirement than traditional cryostats", "It took three years from conception to successfully build a prototype of Quper", "with the fridge offering remote monitoring capabilities via OrangeQS’ open-source operating system, OrangeQS Juice, and SubZero cryogenic control software.", "Fast, compact, simple, but fully functional dilution refrigerators – be it for quantum chip testing and development, optical or beamline experiments, etc. – have been a popular request from our customers for many years, and now we are finally ready to fulfill it,”, "Existing cryostats can traditionally take more than 24 hours to warm up and cool down, with some systems taking multiple days. This can slow research and development efforts for technologies such as new quantum chips."
