Professor Yuri Pashkin


Research Overview

I joined Lancaster University in 2011 to take up a position of Chair of Experimental Condensed Matter Physics. Prior to this I was a Principal Researcher at the research laboratory of NEC Corporation in Tsukuba (Japan).

From 1991 to 1997 I was a visiting scientist at Chalmers University of Technology (Sweden), Physikalisch-Technische Bundesanstalt (Germany) and University of Jyväskylä (Finland).

My research interests include quantum computing with superconducting nanocircuits, quantum metrology with Coulomb blockade devices and nanoelectromechanical systems.
