Quantum technology and quantum metrology research at National Physical Laboratory, UK
Dr. Masaya Kataoka
National Physical Laboratory, Teddington, UK
The UK has been a forerunner in driving the national quantum technology programme, and earlier this year, the government has announced an even larger investment for the next 10 years. The National Physical Laboratory (NPL), as a government laboratory, has been supporting the national efforts to bring various quantum technologies into the market. Our research areas do not only include mainstream applications such as quantum computing and quantum communication, but also the field of quantum electrical metrology aiming to disseminate the so-called “quantum SI” closer to the end users. In this talk, I will first give a brief overview of the quantum technologies research in our Quantum Technologies Department at NPL. I will then describe the research activities of my group (Quantum Electrical Metrology Group) including single-electron transport, explaining what the “quantum SI” really means.
Bio
Dr. Masaya Kataoka
Science Area Leader/Principal Scientist
Masaya joined NPL in 2009, after completing a PhD in semiconductor physics at the University of Cambridge in 2000 and postdoctoral positions held at the Cavendish Laboratory in Cambridge. He also had a brief appointment as a guest researcher at the NTT Basic Research Laboratories in Japan in 2006.
Masaya is currently the Science Area Leader for the Quantum Electrical Metrology Group at NPL, and also leads the Single Electron Device team. He also holds a visiting professor appointment at the University of Strathclyde. He has extensive collaboration with other NMIs, universities, and other research institutes. He was the Coordinator of the European Metrology Programme for Innovation and Research and Innovation project e-SI-Amp, a collaboration of 10 NMIs and academic institutes developing single-electron primary ampere standards and small-current measurement technique. He has published ~ 80 research papers.
Masaya’s main research interest is in the development of semiconductor single-electron devices. He has expertise in cleanroom III-V semiconductor device fabrication and cryogenic electrical measurements. He has extensive experience in experimental work on quantum Hall effect, Coulomb blockade effect, Aharonov-Bohm interferometry, surface acoustic waves, and single-electron transport. He is currently leading NPL’s research effort towards the most accurate SI ampere standards based on single-electron devices that will support the future primary electrical metrology. Masaya is also developing experimental techniques for electron quantum optics, technologies that will enable a new generation of ultrafast electronic/optoelectronic devices.
