Title:
Theory tools for designing quantum networks

Speaker:
David Elkouss

Abstract:
Recent experimental progress has enabled demonstrations of quantum networks. However, many challenges remain to scale these first demonstrations. While quantum networks share similar high-level challenges with their classical counterparts, noticeable differences render many classical approaches of little use, e.g., the unclonability of quantum information or the need to synchronize the parties sharing an entangled state. Quantum networks require novel strategies to enable long-distance communications as well as tools to quantify achievable rates and place requirements on the quantum hardware. In this seminar, I will introduce recent tools for designing quantum networks and evaluating the feasibility of applications such as quantum key distribution.

Bio:
David Elkouss received a double master's degree in electrical engineering from Universidad Politécnica de Madrid (UPM) and Telecom ParisTech and a Ph.D. in computer science from UPM. His Ph.D. thesis in classical error-correcting codes for the postprocessing of quantum key distribution was awarded the UPM extraordinary dissertation prize. After his Ph.D., he moved to the Universidad Complutense de Madrid to work on quantum Shannon theory. A highlight was the proof that it is necessary to solve an unbounded optimization problem in order to see whether or not a channel has a positive capacity. In 2015, he moved to TU Delft where he was part of the team that performed the first loophole-free Bell experiment. Since 2017, he is an assistant professor at TU Delft.

ABOUT QuTech360 seminars:
QuTech360 is a series of seminars where people of all QuTech divisions have the opportunity to build a deep understanding of the topics researched at QuTech. In each seminar, a quantum expert will guide us through one of the main topics studied in their group.
