Oxford Instruments Nanoscience and Harvard University are working together on the next generation of cryogen-free dilution refrigerators, for application in quantum information processing.
Oxford Instruments launched its flagship Triton cryogen-free dilution refrigerator in 2007 and have since shipped more than 70 systems.
The success of Triton is due to high interest in the technology, which allows fast sample cool down to 10mK without the need for liquid helium and is suited to a range of applications.
Charles Marcus from Harvard University recently purchased another Triton Cryofree dilution refrigerator for quantum information research.
He said: 'We chose the Triton system for its 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 customisation and evolution of our system.' Oxford Instruments is also 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 programme.
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.
