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.
