Valerio Scarani

Valerio Scarani joined NUS and CQT in 2007. He was born in Milan, Italy, in 1972. At the moment of choosing his university degree, he opted for physics with the grand dream of understanding the world. After graduating from Ecole Polytechnique Federale de Lausanne (EPFL) in 1996, he heard about the birth of quantum information science, but the complexities of life led him to a pragmatic PhD thesis in the same university. So he spent the next four years of his life detecting insanely broad NMR spectra from magnetic nanostructures. He was lucky enough to be given a second chance in the year 2000, when Nicolas Gisin offered him a postdoc at the University of Geneva, to work on theoretical quantum information. His luck persists to this day.
