China's Quantum Computer Cracks RSA Encryption, Risks Global Security

Quantum computing has advanced to crack small RSA keys (22-bit), signaling future threats to global encryption standards, though current 2048-bit keys remain secure. Researchers used a D-Wave quantum annealer to refactor factorization as a QUBO problem, also posing risks to SPN ciphers like Prese...
