Abstract

Light plays a crucial role in quantum technologies due to its unique properties, which are harnessed for a range of applications. Quantum optics governs how light behaves, and by manipulating it, one can unlock powerful tools for quantum computing, quantum communication and quantum sensing. Light is not only a convenient carrier of quantum information but also offers unique advantages due to its quantum properties, enabling revolutionary advancements in various fields. We will see how light and in particular photons can be used for encoding quantum bits-qubits, how single photons can be created, measured and manipulated and this can lead to quantum photonics for various applications in quantum technologies.

Bio

Christophe Couteau obtained his PhD in physics from the University of Paris-Saclay in 2006 working on quantum optics with quantum dots. He then spent 3 years as a post-doctorate fellow at the Institute for Quantum Computing at the University of Waterloo in Canada working on quantum cryptography and the foundations of quantum mechanics. He is now a Professor and since 2009, he works at the French University of Technology of Troyes (UTT) in France. He works on quantum photonics, nano-optics and quantum nanodevices. He also spent some time at the University of Oxford and was an adjunct assistant professor at the Department of Electrical and Electronic Engineering of the Nanyang Technological University in Singapore for 4 years, from 2012 to 2016. During this time, he was also a CNRS researcher. He is currently the director of the Laboratory Light, nanomaterials & nanotechnologies, a joint research unit between the UTT and the CNRS and a visiting fellow at the Department of Physics at Oxford University in the UK.
