Chinese Researchers Break RSA Encryption Using Quantum Computing

A research team from Shanghai University reports using D-Wave quantum annealing to reformulate cryptographic attacks as QUBO/Ising problems and to optimize the closest vector problem (CVP), enabling factorization of the integer 2,269,753 and a 50-bit RSA number. Published in the Chinese Journal of Computers, the work suggests potential future risks to traditional cryptography and positions D-Wave systems as promising for public key cryptanalysis, while situating the results within the broader, still-limited landscape of practical quantum-computing attacks on encryption.
