The Quantum Computing and Devices (QCD) group was formed in October 2007 in the Academy of Finland Center of Excellence in Computational Nanoscience (COMP). Since 2012, the premises of our research group has been referred to as QCD Labs. We keep an open mind and explore the most interesting and promising pathways to reach maximal quality and productivity in our research. Our research themes vary from the very fundamental theory of quantum mechanics to applied and experimental physics. The different topics in our research are Bose-Einstein condensates, quantum information processing, nanoelectronics, theory of open quantum systems and fluctuations in nanoscale systems, as well as quantum mechanical current standards.
