Once built, the quantum internet will provide unbreakable encryption in daily communication, secure financial transactions, and much more. Stephanie Wehner, a professor at TU Delft and director of the Quantum Internet Alliance, is leading the effort to create the first prototype by 2029.
With a background in hacking and network security, Wehner’s vision goes beyond just cybersecurity to enable secure delegated computation, where users can access remote quantum processors with cheap devices and make networks more efficient using quantum entanglement, such as optimizing Netflix’s content distribution.
The Quantum Internet Alliance, founded in 2017 and supported by the European Commission, aims to bring together experts to achieve this goal. Wehner’s ultimate dream is to make this technology accessible to everyone from their homes.
“We don’t need the best possible components but rather a combination of components that, together, are good enough to provide something useful for the user.”

The prospect of building a quantum internet that enables secure and high-fidelity quantum communication over long distances is a game-changer. It’s not just about achieving ultimate cybersecurity; it’s about unlocking a plethora of applications that can transform our daily lives.
Dr. Stephanie Wehner’s vision is to create a prototype quantum internet by 2029, which is an ambitious goal. But what is fascinating is her broader vision: she wants everyone to have access to this technology from their homes.
Imagine securely delegating computations to remote processors without compromising your data or intentions and envisioning a future where Netflix can distribute content more efficiently using quantum entanglement.
Stephanie Wehner: From Hacker to Professor of Quantum Communication at TU Delft
Stephanie Wehner is a prominent physicist and computer scientist specializing in quantum communication and quantum networks. Currently a professor at TU Delft in the Netherlands, she is recognized for her groundbreaking contributions to the development of the quantum internet. Wehner’s early fascination with communication systems, especially networked communication, led her to explore the possibilities of the internet before it became mainstream.
She worked as a professional, ethical hacker in the late 1990s, conducting penetration tests and network security analyses, which provided her with a solid understanding of the vulnerabilities and potentials of digital communication.
Her deep interest in secure communication evolved naturally into the realm of quantum communication, an area she has focused on for the past two decades. Quantum communication, underpinned by the principles of quantum mechanics, offers the promise of virtually unbreakable encryption and secure transmission of data, which has profound implications for cybersecurity and privacy in the digital world. Wehner’s career has been driven by the goal of building a quantum internet, an ultimate form of networked communication that incorporates quantum technologies.
As the director of the Quantum Internet Alliance, a collaborative European initiative supported by the European Commission, Wehner leads the effort to create a prototype quantum internet by 2029. Her vision extends beyond the lab, as she strives to make quantum communication technologies accessible to users globally, with potential applications in secure financial transactions, delegated computation, and efficient data distribution.
Wehner’s work involves not only the technical development of quantum internet infrastructure but also the collaboration between diverse fields such as electrical engineering, computer science, and experimental physics. Through her leadership, she is guiding the transition of quantum communication from theoretical physics experiments to practical, engineering-driven solutions.
The potential applications are vast and varied. From location-based identification for secure access to critical infrastructure control systems, the possibilities are endless. Dr. Wehner’s emphasis on creating a user-friendly experience is crucial; it’s not just about showcasing cutting-edge technology but making it accessible and valuable for everyone.
As Dr. Wehner aptly puts it, “We don’t need the best possible components but rather a combination of components that, together, are good enough to provide something useful for the user.” This pragmatic approach is essential for turning the quantum internet from a theoretical concept into a tangible reality.
