Alexandre Blais is an Associate professor of theoretical physics in the Department of Physics at the Université de Sherbrooke, Québec Canada. After receiving his Ph.D. from the Université de Sherbrooke in 2002, he worked as a postdoctoral researcher at Yale University (2003–2005). His research interests are at the intersection of nanophysics and quantum optics, and focus on superconducting qubits and circuit quantum electrodynamics. He is a fellow of the Quantum Information Science and the Quantum Materials programs of the Canadian institute for advanced research.
Preparing a harmonic oscillator in a state with a well-defined energy is a tricky business. With the new tools provided by cavity and circuit quantum electrodynamics it is now possible to make these pure quantum states and watch how they evolve in time.
