In a significant leap towards the Quantum Internet, Deutsche Telekom and Qunnect have demonstrated exceptional capabilities in sustaining high fidelity transmission of entangled photons across a commercial fibre network. During an experiment in Berlin, they achieved 99% fidelity over 30 kilometres for a remarkable 17 days. This breakthrough solidifies the foundation for future developments in quantum communication technology, merging scientific exploration with practical application.
The fibre-optic test track allowed for the distribution of polarization-entangled photons while automatically compensating for varying environmental conditions. This achievement surpassed prior records in metropolitan networks, showcasing an impressive reliability with just 1% downtime. Additionally, simultaneous routing of these photons alongside classical data traffic across 82 kilometers also achieved over 92% fidelity.
For quantum internet functionalities to expand beyond simple secure links, the distribution of useful qubits is essential. The successful deployment of polarization qubits in this experiment highlights their potential compatibility with various quantum devices. Maintaining stability of quantum particles within the grid remains a challenge, with current success limited to short distances in lab settings.
Entanglement technology can enhance quantum key distribution, fostering ultra-secure communication for corporations and public institutions. Beyond safety, it also opens opportunities for precision timing synchronisation in satellite networks and accurate sensing in industrial Internet of Things (IoT) applications.
Qunnect’s CEO, Noel Goddard, praised their collaboration with T-Labs and Deutsche Telekom as pivotal for showcasing the practical utility of quantum networking amid classical data traffic. Claudia Nemat from Deutsche Telekom added, “Our fiber optics are ready for the Quantum Internet, even today,” emphasising their commitment to innovation and security.
T-Labs’ research strategy targets the integration of cutting-edge quantum technologies into telecommunications, promoting advancements in cybersecurity. The creation of their Quantum Lab in Berlin in 2023 is a testament to such ambitions, establishing connections with over 2,000 kilometres of fibre-optic network to facilitate progressive research.
As Deutsche Telekom’s dedicated research arm, T-Labs engages in co-creation initiatives with academic bodies and startups, focusing on evolving network technologies, including quantum systems and security measures. Meanwhile, Qunnect’s innovative approaches are transforming existing fibre optics into functional quantum networks, building on their pioneering work in quantum memory since 2021.
Both companies are paving the way for a new era in secure, efficient telecommunications, establishing a robust foundation for the Quantum Internet of the future.
