Quantum network technology

Quantum network technology Prof Dr Stephanie Wehner, Director of the European Quantum Internet Alliance, explains how quantum network technology and a quantum internet could revolutionise communication and connectivity. The internet, an intricate network connecting devices across the globe with classical communication, has profoundly shaped our world. We now stand on the brink of a new type of internet. Imagine an evolution of the internet, one that intertwines the principles of quantum mechanics with our existing digital technology. This is the vision of a quantum internet - an innovation that promises to redefine our understanding of communication and connectivity. Working in tandem with our traditional ‘classical’ internet, a quantum internet would connect quantum devices globally. Such a network would unlock capabilities that are fundamentally unattainable through classical communication alone. Take, for instance, Quantum Key Distribution (QKD), a striking application of quantum communication. QKD allows two distant nodes to create an encryption key guarded by the immutable principles of quantum mechanics.
