Oxford Instruments’ TritonXL Cryofree dilution refrigerator selected for the Oxford NQIT Quantum Technology Hub project
26 June 2015

Oxford Instruments is pleased to announce that its latest Cryofree® dilution refrigerator TritonXL has been chosen to support the Networked Quantum Information Technologies (NQIT) Quantum Technology Hub, led by the University of Oxford. The TritonXL is Oxford Instruments’ newest Cryofree dilution refrigerator platform, with a base temperature of less than 5 mK, cooling power of up to 1000 µW at 100 mK, and a 430 mm diameter mixing chamber plate. These features allow experimentalists an even greater range of options for sample size, wiring, and magnet integration than was previously possible, while continuing to offer Oxford Instruments’ leading top- and bottom-loading sample exchange options.

The Oxford NQIT system, with the 1000 µW cooling power, will be used in the development of superconducting quantum circuits by Dr Peter Leek’s group of researchers in Condensed Matter Physics within the Hub. The TritonXL platform builds on the established success of the Triton dilution refrigerator, which has over 250 units installed worldwide.

This TritonXL system is the first of this type of large platform dilution refrigerator to be delivered to a customer in the UK. Such systems have been growing in popularity within the Quantum Sciences community, including a system with an integrated 16 Tesla superconducting magnet at the Indian Institute of Science (IISc), Bangalore, India, as well as several in the United States.

The NQIT Hub, part of the UK National Quantum Technology Programme, is led by the University of Oxford and involves 29 globally leading quantum centres and major companies, all working together to realise an entirely new technology sector. The Hub's focus is on systems that can connect together to form flexible, scalable solutions for diverse applications. These powerful principles of flexibility and scalability have made the network the single most important concept in modern information technology, with incalculable beneficial impacts on society. The overall network can achieve things that are effectively impossible with conventional technologies.

“Oxford Instruments has considerable past experience in moving technology and methods from research labs into real product development, in application areas related to quantum technology. The new TritonXL system will be a quantum-ready cryogenic platform that allows us in our NQIT project to develop larger scale superconducting circuit prototypes, bringing us closer to realising a practical quantum computer using this technology”, says Dr. Peter Leek.

Oxford Instruments is proud to be a leading UK company providing state of the art research tools for the development of quantum technology applications, having extensive relationships with both the worldwide research community and companies bringing new commercial applications to market.

Dr Michael Cuthbert, Managing Director of Oxford Instruments NanoScience commented, “Oxford Instruments is committed to its part in delivering the success of NQIT and the other Quantum Technology Hub projects in which we are participating. To this end, we are also sponsoring a PhD student within NQIT working to develop quantum device measurement capability at ultra low temperatures.”
