Researchers Make the First Quantum Leap Across the Atlantic: An Unhackable Internet Is Coming
Introduction
Marconi’s Echoes, A Quantum Prospect. In 1901, more than 120 years after Guglielmo Marconi sent the first transatlantic radio transmission, scientists are once again trying to use invisible signals to connect continents, but this time, they want to use essentially unhackable communication. Through the HYPERSPACE project, researchers in Canada and Europe are leading this ambitious endeavour by creating satellite-based technology that will enable the transmission of quantum-coded messages over great distances.
By using space for ultra-secure communication, this project is paving the way for a new form of internet that goes beyond the constraints of fiber-based quantum communications. HYPERSPACE seeks to remove the fundamental scientific and technological barriers that stand in the way of a transatlantic quantum link becoming fully functional, even though this milestone is still years away.

Quantum Communication
The Unhackable Promise: Quantum Communication Explained
Explaining Quantum Communication HYPERSPACE’s mission is centered on the promise of communication that is really secure. When it comes to quantum communication, eavesdropping is impossible, unlike regular encryption, which can eventually be cracked by powerful computers. Intercepting quantum transmissions reveals eavesdroppers and disrupts links. Alternatives to complex passwords and procedures include fundamental physics and entanglement, which Einstein called “spooky action at a distance”.
In a straightforward example, linked particles exhibit identical twin behaviour. Even if they live hundreds of miles apart, if these “twins” each have one of two eye colours (brown or blue), figuring out the colour of one instantly discloses the colour of the other. Their eye colour is not known until it is measured, which is a distinctive feature of quantum theory. Both twins had the same findings from these measurements, which are entirely random. Because of this innate randomness and quick correlation, scientists are able to safely construct random encryption keys, which are secret codes behind sealed communications that are impossible for even future supercomputers to copy or eavesdrop on.
Space Advantage
The Space Advantage encryption keys are currently shared by photons via fiber-optic cables in the majority of quantum communication systems. Nevertheless, ground-based fiber-based systems have serious drawbacks; after just a few hundred km, signals deteriorate and lose their dependability. In order to facilitate safe communication between continents, the HYPERSPACE team is focusing on space and investigating the possibility of transmitting quantum signals between satellites and ground stations. Space-based quantum communication has been shown by China’s Micius satellite’s successful transmission of quantum signals between Asia and Europe. By creating the tools and protocols required for a safe, transcontinental quantum connection, HYPERSPACE hopes to bridge the Atlantic and open the door for a genuinely worldwide quantum internet.
Using High-Dimensional Entanglement to Increase Security and Capacity. In order to enable a worldwide quantum internet, the HYPERSPACE team is also investigating the process of “high-dimensional entanglement,” which involves encoding multiple quantum bits (qubits) onto a single photon. More information is essentially packed into each gearbox as a result. For example, high-dimensional entanglement is like “adding extra lanes to the road,” whereas ordinary quantum entanglement usually only permits one piece of information to be communicated at a time (like one automobile on a single-track road). Multiple “vehicles” or bits of information can now travel side by side, facilitating faster data transfer with fewer interruptions or slowdowns.

According to the research organizer, Professor Dr. Fabian Steinlechner, high-dimensional entanglement also greatly improves the resilience of the system.” Due to its distribution across multiple channels, the signal is robust even when it is subjected to interference, such as noise or hacking attempts. Basically, this invention offers more information to be contained in each quantum light pulse, faster speeds, and increased security.
Establishing a Quantum Internet Foundation. The idea of a space-based quantum internet is still in its infancy, but HYPERSPACE is now focused on establishing a proof of concept with shorter terrestrial free-space optical lines. Building and extensively testing the fundamental technologies required for safe quantum communication between Europe and Canada is the main objective of the project. This covers the complex protocols for high-dimensional entanglement as well as sophisticated photons. Should this groundbreaking effort be successful, it would provide a model for upcoming intercontinental quantum networks, eventually resulting in a fully functional quantum link.
The long-term goal goes beyond secure communication to include a global infrastructure for cloud computing, improved sensing, secure data sharing, and accurate navigation, the so-called quantum internet. Physical laws make all of these apps hack-proof.
International Collaboration and European Leadership
The HYPERSPACE project, which is supported by the Government of Canada and the European Union (EU) through the Horizon Europe initiative, is an example of international collaboration. The Quantum Flagship and Canada’s Natural Sciences and Engineering Research Council (NSERC) also provided significant assistance. For the purpose of transferring quantum communications from lab tests to actual spaceborne networks, Europe has taken the lead globally in two areas: quantum optics and photonic integration.
A strong group of scientists from eight top academic institutes in Europe and Canada comes together as part of the HYPERSPACE consortium. The Universities of Padua and Pavia in Italy, CEA-Leti in France, TU Wien in Austria, Fraunhofer IOF in Germany, and the Institut National de la Recherche Scientifique, the University of Toronto, and the University of Waterloo in Canada are also among these establishments. To demonstrate high-dimensional quantum entanglement transmission across actual air linkages, this consortium is constructing the full technical chain, from detectors and space-compatible optical systems to quantum light and signal encoders. The consortium is expected to wrap up its work this September.
