Q

QuantumCTek (国盾量子) is China's largest publicly-listed commercial QKD vendor by deployed network footprint and the hardware supplier behind the national quantum-secure communication backbone. Spun out of Pan Jianwei's University of Science and Technology of China (USTC) group in Hefei in 2009, it listed on the Shanghai STAR Market in July 2020 (688027) as China's first publicly traded quantum company. Its decoy-state BB84 terminals equip the Beijing–Shanghai trunk, metro QKD networks, and the Micius satellite ground stations. Product range also covers QRNGs, quantum-secure VPN gear, single-photon detectors, key- management systems, and (since 2022) superconducting quantum computers.
