Oxford Instruments and Harvard University to Develop Next Generation Cryogen-Free Dilution Refrigerators

Oxford Instruments NanoScience and Harvard University are working together on the next generation of cryogen-free dilution refrigerators. Oxford Instruments launched its flagship Triton cryogen-free dilution refrigerator in 2007 and have since shipped over 70 systems.

The success of Triton is due to high interest in the new technology allowing fast sample cool down to 10 mK without the need for liquid helium and also the range of applications it is suited for. One key application of Cryogen-free dilution refrigerators is Quantum Information research. Charles Marcus from Harvard University recently purchased another Triton Cryofree dilution refrigerator, demonstrating the suitability of this product to this particular application. He commented: "When we were looking at options for a new cryogen-free dilution refrigerator, we chose the Triton system for his ability to rapidly cycle samples to base temperature, including dc and rf connection capability. We also like the modularity of the sample slug system allowing customization and evolution of our system."

Oxford Instruments is also delighted to be part of the Multi-Qubit Systems Based on Electron Spins in Coupled Quantum Dots project, which is a consortium led by Charles Marcus of Harvard University and funded by the Intelligence Advanced Research Projects Activity as a part of its Multi-Qubit Coherent Operations program.

Collaborators include Harvard, Oxford Instruments, UC Santa Barbara, University of Maryland, TU-Delft, University of Sydney, University of Tokyo and University of Basel. The consultancy team at Oxford Instruments will be focusing on developing the Ultra Low Temperature instrumentation required for these experiments, including high density high bandwidth wiring schemes.
