Hefei Guoxing Quantum Shield Technology Co., Ltd. ("Guoxing Quantum" for short), founded in 2023 and headquartered in the Quantum Information Industry Base of Hefei High-tech Zone, China, is a world-leading full-stack, all-industry, all-scenario quantum security service provider spanning "quantum satellite constellation - space quantum cloud - cloud - network - edge - device - chip." It is also the only private quantum technology company in China to integrate the entire industrial chain of "satellite-borne quantum security payload development - LEO quantum satellite constellation operation - chip-level hardware root of trust - space-ground integrated key system - all-industry scenario deployment."
With the mission of "building a global security barrier for the quantum era and safeguarding a trusted digital future for the Belt and Road," the company builds on its independently developed "QKD + QRNG + PQC + Chinese national cryptographic algorithms" four-in-one full-stack quantum security technology system, deeply integrating space-ground quantum communication capabilities with the strengths of classical cryptography to create a full-chain quantum security product matrix covering space, cloud, links, edge, devices, and chips.
Guoxing Quantum focuses on delivering blind-spot-free, quantum-resistant, and fully compliant end-to-end quantum security solutions for high-security customers worldwide, including Chinese embassies and consulates abroad, overseas offices of state-owned and central enterprises, border defense and military base stations, large multinational corporations, governments of countries along the "Belt and Road," as well as the government affairs, finance, energy, and electric power sectors. These solutions fundamentally address core industry pain points such as cross-border communication data leaks, the absence of terrestrial network coverage in remote areas, the risk of quantum computers breaking traditional cryptographic systems, the difficulty of multinational compliance adaptation, and the lack of long-term security guarantees for core data assets.
The company adheres to a development philosophy of "technology-driven, compliance-first, deep scenario focus, and global presence," investing no less than 35% of its annual revenue in R&D. It has successively obtained multiple national- and industry-level certifications, including commercial cryptographic product certification from the State Cryptography Administration, information security certification for the power industry, data security certification for the financial industry, and product testing certification for classified military information systems. It also fully conforms to globally authoritative compliance requirements such as NIST PQC standards, Common Criteria CC EAL5+, FIPS 140-3, and GSMA, giving it full-compliance service capabilities for multinational scenarios.
As of December 2026, Guoxing Quantum has served more than 100 government and enterprise customers worldwide, with deployed projects covering six core industries — government affairs, finance, energy, telecommunications, defense, and diplomacy — and over 5 million end users served cumulatively. It has become a benchmark enterprise in the global industrialization of quantum security, and a core representative of China's quantum technology and commercial aerospace sectors "going global."
