Quantum Internet E-Commerce. The recent development in quantum internet technology in China marks a significant milestone in the realm of secure e-commerce. Researchers have successfully conducted what they describe as the first “unhackable” shopping transactions using a small quantum computing network. This achievement not only paves the way for a more secure online shopping experience but also showcases the practical applications of quantum technology in everyday life.
The project was spearheaded by Hua-Lei Yin from Renmin University of China, along with his colleagues. They constructed a modest network using five quantum computers linked by several kilometers of fiber. The network’s primary function is based on manipulating the quantum properties of light, a key characteristic of all quantum networks. This innovative approach is a departure from traditional e-commerce platforms, which rely on classical encryption algorithms for security. These conventional methods, while effective against most cyber threats, are potentially vulnerable to powerful quantum computing, which can break these encryptions.
Quantum technology, in contrast, offers a fundamentally different approach to secure communication. It leverages the principles of quantum mechanics, particularly quantum entanglement, to create a system that is theoretically immune to hacking. In this context, the researchers employed a quantum digital signature (QDS) approach, integrating quantum secret sharing and one-time universal hashing. This method ensures the integrity, authenticity, and non-repudiation of transactions, addressing a significant challenge in quantum e-commerce – preventing message senders from denying offers they have already made in transactions.
In their experiment, the team demonstrated a five-user quantum network using this protocol, showcasing its potential for real-world application. The quantum network can ensure that contract signing and payments are executed swiftly and accurately, without the need for a trusted third party to be identified in advance. This not only enhances security but also improves efficiency in e-commerce transactions.
Associate Professor Yin Hualei highlighted the significance of this development, stating that their work contributes to the further evolution of e-commerce in the quantum era by providing a practical and efficient solution with enhanced security. This achievement is a crucial step towards realizing the potential of quantum internet, which promises to revolutionize the way we conduct online transactions and communicate over the internet.
As we advance further into the quantum era, such developments indicate a future where quantum technology is not just a subject of academic research but a practical tool enhancing various aspects of daily life, including online commerce. The successful implementation of unhackable transactions in a quantum network lays the groundwork for more widespread adoption and continued innovation in this field.
