Brooklyn, United States – Qunnect, a provider in quantum-secure networking technology designed for scalable deployment on existing telecom fibre infrastructure, debuted their QU-APC instrument with an interactive demo on the exhibit floor of the 2023 OFC Conference in San Diego. The 2023 Optical Fiber Communication Conference and Exhibition (OFC) is the conference and exhibition for optical communications and networking professionals.
Qunnect’s QU-APC (auto polarisation compensator) is a real-time calibration and compensation solution to maintain high-fidelity transmission of quantum information over telecom fibre. Commercial fibre is typically deployed as aerial cables or buried in conduit near roadways. These cables are subject to numerous environmental perturbations such as wind, temperature, and vibration, which can damage the quantum information being transmitted through them. The QU-APC alternates between test and transmission modes, utilising rapid measurement and analysis to maintain >95% quantum transmission uptime. With insertion loss of only 1.2dB, the QU-APC is an provider in quantum-enabling technologies.
“The QU-APC is a game-changer for addressing the challenges of real-world quantum networking,” notes Qunnect CEO Noel Goddard, “We are very pleased to announce the commercial launch of this product as a qubit-agnostic solution for both Distributed Entanglement and QKD protocols.”
On the exhibit floor of OFC, the Qunnect team invited visitors to jump on a floor mat covering a spool of fibre. Participants observe the disturbance in the fibre’s transmission fidelity on a nearby screen, and then see the QU-APC correct for the disturbance in real time, restoring the fidelity. While this is an extreme example of real-world perturbations, it demonstrates the power and speed of the QU-APC to compensate for these issues.
