The Quantum Internet | Stephanie Wehner | TEDxVienna

The goal of a quantum internet is to connect quantum processors using long distance quantum communication. The internet has had a revolutionary impact on our world. The long-term vision of this talk is to build a matching quantum internet that will operate in parallel to the internet we have today. This quantum internet will enable long-range quantum communication in order to achieve unparalleled capabilities that are provably impossible using only classical means. Stephanie starts by exploring what a quantum internet is good for, and gives an intuition why quantum communication is so powerful. She proceeds from the state of the art today, towards stages for a full blown quantum internet. As an example, she discusses the efforts of the EU quantum internet alliance including the planned demonstration network connecting four Dutch cities in 2020. Stephanie Wehner is an Antoni van Leeuwenhoek Professor at QuTech, Delft University of Technology, where she leads the Quantum Internet efforts. Her passion is the theory of quantum information in all its facets, and she has written numerous scientific articles in both physics and computer science. In a former life, she worked as a professional hacker in industry. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
