Triton: advances in dilution refrigerator technology for quantum info processing

In this webinar Prof. Charles Marcus presents an overview of his work using the Triton dilution refrigerator at the Niels Bohr Institute’s Center for Quantum Devices, University of Copenhagen. He reviews the latest advances in dilution refrigerator technology for QIP, specifically focusing on the integration of high-density RF interconnects.

The scaling of single- or few-electron spin-qubit devices to multi-qubit architectures presents a challenge to cryogenic technology. Particularly demanding is the integration of large numbers of RF interconnects to samples operating at millikelvin temperatures in high magnetic fields within physical space, heat load and electrical noise limits. With its advanced sample loading, integrated magnet solutions and quantum information processing (QIP)-specific wiring options, the Triton dilution refrigerator has been adopted as the system of choice for studies in this exciting area of emerging technology.

In this webinar we review the latest advances in dilution refrigerator technology for QIP, specifically focusing on the integration of high density RF interconnects. To illustrate this, Prof. Charles Marcus presents an overview of his work using the Triton dilution refrigerator at the Niels Bohr Institute’s Center for Quantum Devices, University of Copenhagen.

Date: Friday 5 April 2013

Speaker: Prof. Charles M Marcus, director, Center for Quantum Devices at the Niels Bohr Institute, University of Copenhagen
Professor Marcus’ work in experimental condensed-matter physics is focused on the physical realizations of QIP systems and quantum coherence in electronic devices. He received his PhD from Harvard University in 1990 and was a professor of physics at the university between 2002 and 2011.

Speaker: Dr David M Haynes, business development director of Oxford Instruments, Omicron NanoScience
Dr Haynes is responsible for product developments in a wide range of application areas including QIP and 2D materials. He has more than 15 years’ experience in the commercialization of emerging fabrication technologies for optoelectronics, photonics, data storage, MEMS and advanced chip scale packaging technologies. He received his PhD from Swansea University in 1995.
