A team of researchers in China, led by Wang Chao at Shanghai University, successfully factored a 22-bit RSA integer using a quantum annealing processor from D-Wave Systems. This is a significant step as it demonstrates the potential of quantum computers to address cryptographic challenges and has prompted warnings from security experts about the future of data security.

However, it's important to note that the 22-bit key factored is much smaller than the 2048-bit RSA keys commonly used today for production. This research scaled beyond previous demonstrations and required fewer qubits per variable, which could pave the way for breaking larger keys in the future.
