Quantum Mirrors
Prof. Valerio Scarani
Department of Physics, National University of Singapore

What happens if some devices, that we are accustomed to think of as classical, were replaced by quantum devices? We started exploring this broad question with atoms in one-dimensional waveguides, which are obviously quantum objects and behave as mirrors in the suitable regime. In this talk, after introducing the basic motivation and physics, I'll present some of our recent results:

-- Scattering of 2, and N photon by an atom: A. Roulet et al., Phys. Rev. A 93, 033838 (2016); arXiv:1603.02804.
-- A light diode made of two atoms: J. Dai et al., Phys. Rev. A 92, 063848 (2015).
-- Cavity QED with quantum mirrors made of N atoms: P.-O. Guimond et al., Phys. Rev. A 93, 023808 (2016).

About the Speaker

Prof. Valerio Scarani is a leading expert in theoretical quantum physics, doing complex research in various fields of quantum information, such as quantum non-locality, quantum key distribution, device-independent randomness generation, quantum optics and assessment of experiments. He has led a research group in Singapore since 2007 and won Singapore’s National Science Award in 2008. Previously, he received his PhD in 2000 from Ecole Polytechnique Federale de Lausanne, Switzerland, and worked in the group of Nicolas Gisin at the University of Geneva, Switzerland. He has about 130 publications in peer-reviewed journals including Rev. Mod. Phys, Science, Nature, Nature Physics, Nature Communications, Phys. Rev. Lett. Moreover, he has written two introductory books on quantum physics.
