Short biography
Levon Chakhmakhchyan received his M.S. in Theoretical Physics from Yerevan State University, Armenia, in 2011. The same year he started his doctoral studies in physics, under international joint supervision between France (Université de Bourgogne) and Armenia (Institute for Physical research), funded by the Conseil Régional de Bourgogne, CNRS and the State Committee of Science of Armenia. In summer 2012 he was an early stage researcher at the Ultrafast Quantum Optics and Optical Metrology group of the University of Oxford, within FP7's Marie Curie ITN project FASTQUAST. As of 2015, after obtaining his PhD degree, he is a postdoctral fellow at QuIC and is funded by the H2020's FETProActive project QUCHIP.
