Alexander Tzalenchuk received a diploma in Electronics Engineering from the Department of Crystal Physics, Faculty of Electronic Materials and Devices, Moscow Steel & Alloys Institute and a PhD. degree in Physics and Mathematics from A.V.Shubnikov Institute of Crystallography Russian Academy of Sciences. Alexander more than 30 years of experience in solid-state physics, nanotechnology and quantum metrology. In his early days in Moscow he studied charge transport in semiconducting and fast-ion conducting bicrystals. Later he spent over 10 years at Chalmers University of Technology in Gothenburg, Sweden, investigating Josephson devices in high-Tc superconductors (HTS). In particular he worked on the development of submicron technology for the HTS materials and studied a range of mesoscopic effects in ultrasmall HTS Josephson junctions.
Alexander joined NPL in February 2002. He was appointed as a Visiting Professor (2008) and then Professor of Physics in the Physics Department of the University of London’s Royal Holloway College (2013). In 2016 he was appointed as an NPL Fellow. NPL Fellowship is a recognition of individual merit awarded to scientists who are making very significant contributions to NPL's scientific achievement and standing. It is a particular distinction that acknowledges and rewards significant scientific accomplishments and leadership.
Areas of interest
Alexander has been involved in a number of projects concerning quantum metrology, magnetic and superconducting macroscopic quantum systems, single particle detection, terahertz photon counting, scanning probe microscopy. His latest and ongoing projects focus on two areas of science: physics of advanced materials (2D, unconventional superconductors) in application to quantum electrical metrology and research underpinning scalability of superconducting quantum computers. Alexander oversees science planning and delivery in the Quantum Detection group, presently comprising about 50 FTE researchers.
