Quantum Information & Quantum Computation

Welcome to my homepage!

This website contains all the information about my academic interests, research and publications and all scientific contribution. As well as resources for students, researchers, current research problems, and blog. Abstract theme of my research is at the intersection of Quantum Information and Quantum Computation with Condensed Matter and Quantum Optics. I support open access to scientific information and thus you will find all my articles via this website to pre-print repositories and/or journal published copy.
