In a groundbreaking achievement for quantum communications, Deutsche Telekom and Qunnect have made significant strides in developing the quantum internet. Working from Deutsche Telekom Innovation Laboratories (T-Labs) in Berlin, they achieved a remarkable 99% fidelity in entangled photon transmission over 30 kilometres for an extended 17-day period, surpassing previous records. This experiment represents a pivotal moment for future quantum communication technologies.
Conducted within T-Labs’ quantum lab, this first-of-its-kind field trial showcased the transmission of entangled photons on an operational fibre-optic network. The researchers successfully demonstrated the viability of sustaining high-fidelity entangled photon communications over substantial distances, marking a new era for quantum technology in the real world.
Using polarization-entangled photons, the team efficiently maintained a 99% fidelity by automatically adjusting to external interferences that could disrupt transmission. Remarkably, the system experienced only 1% downtime, breaking records for similar technologies and underscoring its reliability in practical applications.
Moreover, in a complementary experiment, entangled photons were routed dynamically across 82 kilometres of fibre-optic paths while maintaining fidelity levels above 92%. This represents the longest high-fidelity entanglement distribution demonstration yet, merging O-band multiplexing with C-band classical data transmissions.
Noel Goddard, CEO of Qunnect, expressed gratitude towards T-Labs and Deutsche Telekom, highlighting the importance of collaboration in advancing quantum networking technologies. Meanwhile, Claudia Nemat of Deutsche Telekom affirmed their readiness for the Quantum Internet, stating, “Our fiber optics are ready for the Quantum Internet, even today,” and noted the advantages such innovations bring to customers, including enhanced security in communications.
Deutsche Telekom and Qunnect have achieved a notable milestone in quantum internet development by demonstrating 99% fidelity in entangled photon transmission over a 30-kilometre distance for 17 days. This experiment, the first of its kind on a commercial fibre network, showcases advancements in quantum communication technologies, with implications for future secure communications.
Deutsche Telekom and Qunnect’s collaborative breakthrough in quantum internet technology signifies a substantial leap in the realm of communications. Their successful transmission of entangled photons over a commercial network demonstrates both reliability and potential for practical applications. This advancement not only reflects ongoing technological progress but promises to enhance secure communications for customers in the near future.
