Nowadays, the classical Internet is mainly envisioned as the underlying communication infrastructure of the Quantum Internet, aimed at providing services such as signaling and coordination messages. However, the interplay between the classical and the quantum Internet is complex and its understanding is pivotal for an effective design of the Quantum Internet protocol stack. The aim of the article is to shed light on this interplay, by highlighting the fact that such an interplay is indeed bidirectional rather than unidirectional. The Quantum Internet exhibits the potential of supporting and even enhancing classical Internet functionalities.

ost of us use the internet every day.Whether to message our friends on social media, research a topic we want to know more about, or do some online shopping, the internet has become an integral part of our lives.The current version of the internet, however, is liable to being attacked.News reports tell stories of hackers who reveal individuals' credit card details, health records or other sensitive information.This is why Associate Professor Jacquiline (Jacq) Romero at the University of Queensland is helping to develop the quantum internet -a new version of the internet that will provide the most secure kind of communication possible within the laws of physics. How is the quantum internet different to the regular internet?The current internet works by using 'bits' that are always in one of two physical states, like the on/ off switch of a light or TV.The state of these bits is usually represented by a single binary value, either 0 or 1. "The quantum internet differs from the regular internet because it will transmit quantum information ('qubits') instead of classical information ('bits')," says Jacq. "Quantum states are very different."
