(ZDNet) A team of researchers from the NUS-Singtel Cyber Security Research & Development Laboratory in Singapore have demonstrated a new technique to advance quantum key distribution (QKD).  The breakthrough was demonstrated over Singtel’s fibre network, with NUS associate professor Alexander Ling saying the positive results indicate that current commercial fibre networks are ready for QKD. The team succeeded in coordinating the travel of a pair of photons — one for each party — through different fibre network paths and were able to precisely control the photons’ arrival times.
“The breakthrough achieved by the NUS-Singtel Cyber Security R&D Lab not only strengthens our defences in a new cyber reality where threats are becoming more sophisticated, it also positions Singapore as a hub for global QKD research. We will continue developing and fine-tuning this technology with the aim of commercialising it through our global footprint of product engineering centres,” Singtel Group Enterprise CEO Bill Chang said.
