Quantum chip network boosts data security
In a move that could revolutionise data security, researchers in China have developed a new chip-integrated quantum network that offers both high-speed and cost-effective digital signatures, making it viable for widespread use across industries.
Chinese scientists have developed a compact chip-based quantum digital signature network that drastically improves both speed and efficiency.
The system replaces bulky, expensive equipment with streamlined silicon chips, making it easier to integrate into today’s fibre networks.
The new setup allows multiple users to share a single central detector, reducing cost and complexity. By adopting a star network design and a new cryptographic protocol, the system can handle longer documents with fewer resources and lower delays.
The Chinese experiment outperformed previous quantum signature technologies, achieving reliable performance even over a 200 km fibre link.
Experts say this research opens the door to future applications in quantum e-commerce, secure communication, and digital finance.
