💥China's Quantum Leap Threatens RSA Encryption!

--> ✅️ Staff Writer Chinese researchers at Shanghai University used a D-Wave quantum annealing processor to factor a 22-bit RSA integer, marking a step toward cracking RSA encryption.

--> ✅️ Introduced in 1977, RSA relies on the difficulty of factoring large semiprimes, a task that remains tough for classical computers, with the largest key broken (829 bits) taking weeks on a supercomputer.

👨🏼‍🚀👉 The team converted factorisation into a problem solvable by D-Wave’s Advantage system, where qubits find the lowest energy state.

--> ✅️ They also applied this method to Substitution-Permutation Network ciphers like Present and Rectangle, claiming it’s the first real quantum threat to these widely used algorithms.
