Hybridnet: Hybrid quantum networks, light and matter - Julien Laurat

Hybrid Quantum Networks (HybridNet)

The field of quantum information was developed with the idea of exploiting the peculiarities of the quantum world to accomplish tasks that are difficult or impossible with traditional methods of information processing, for example: communication and quantum computing.

 

The HybridNet project’s goal is to develop the building blocks of "quantum networks" to distribute and process quantum information. In these networks, where information is conveyed by the light and made of nodes, light and matter would exchange their states on demand, enabling quantum communication over long distances. This project will explore in particular a "hybrid" implementation of those networks, where the corpuscular and wave aspects of light are operated simultaneously. New information storage devices in laser-cooled atoms that are trapped around the optical fibers and quantum gates for processing of this information will be developed especially for this network.

 

After studying at the Institut d'Optique Graduate School, Julien Laurat wrote his thesis at the Kastler-Brossel laboratory under the direction of Claude Fabre and Thomas Coudreau. His work has focused on the generation of entanglement using optical parametric oscillators (2004). He then joined the team of Philippe Grangier at the Institut d'Optique where he studied 'Schrödinger cat' optical states. He then completed a fellowship in the group of Jeff Kimble at the California Institute of Technology. His work has focused on light-matter interaction and has enabled the interfacing of sets of atoms and single photons. He therefore demonstrated early versions of elementary quantum networks. Julien Laurat was recruited at the Kastler-Brossel Laboratory in 2007 as an associate professor at UPMC, and became a full professor in 2013. Since then, he has worked in the Quantum Optics team on distribution and quantum information processing. In 2011, Julien Laurat was winner of the City of Paris “Emergence” call for projects and nominated to the Institut Universitaire de France.
