Chinese researchers claim to have made a breakthrough in quantum computing, demonstrating the ability to compromise symmetric encryption algorithms using quantum-based techniques. The research, published in the Chinese Journal of Computers, details the use of the D-Wave Advantage quantum processor to attack lightweight encryption ciphers such as PRESENT, GIFT-64, and RECTANGLE. However, there are questions surrounding the validity of the research and the accuracy of media reports surrounding it. The researchers used a quantum annealing algorithm, which has limitations in its effectiveness against modern cryptographic algorithms. This breakthrough requires further investigation and validation before it can be considered a genuine threat to contemporary cryptography.
In a significant development for global cybersecurity, Chinese researchers have unveiled a method using D-Wave’s quantum annealing systems to crack classic encryption, potentially accelerating the timeline for when quantum computers could pose a real threat to widely used cryptographic systems. The research team, led by Wang Chao from Shanghai University, found that quantum annealing can optimize problem-solving in a way that makes it possible to attack encryption methods such as RSA. They successfully factored a 22-bit RSA integer, demonstrating the potential for quantum machines to tackle cryptographic problems. This raises serious questions about the future of cybersecurity and the need for robust quantum-safe or post-quantum cryptographic solutions to protect sensitive information.
