On 17 April, Vodafone Portugal conducted its first video call using Quantum Key Distribution (QKD), connecting three locations in Lisbon via Vodafone Portugal’s fibre optic network. The QKD call was made possible using QuKy, a platform developed by Italian quantum encryption company ThinkQuantum.
The demonstration linked the Vodafone Innovation Hub to a Vodafone data center and to the Quantum Technologies Laboratory (QuTe Lab) of the Instituto Superior Técnico and the PQI – Portuguese Quantum Institute.
According to Vodafone, the purpose of the test was to demonstrate the capacity of its network to support emerging technologies associated with the next generation of cybersecurity. This, said the announcement, marks a crucial first step towards initiating quantum communications, was developed at the Vodafone Innovation Hub, Vodafone Portugal’s collaboration and innovation center.
ThinkQuantum’s QuKy platform, which was used for this trial, is designed to integrate with existing network infrastructure using a three-node topology, with optical switching at the central node meant to simplify the architecture and reduce the number of devices required.
By enabling this trial in a real-world environment, Vodafone demonstrates that its network is prepared for future technological evolution and the integration of advanced security solutions based on the principles of quantum physics. Simultaneously, it reinforces its commitment to anticipating technological trends, supporting the innovation ecosystem, and collaborating with companies and academic institutions in developing solutions that address the future challenges of the digital society.
