The research team, led by Wang Chao from Shanghai University, found that D-Wave’s quantum computers can optimize problem-solving in a way that makes it possible to attack encryption methods such as RSA.

The headline should mention that they're breaking 22-bit RSA, but then it would get a lot less clicks.

A different group of Chinese researchers set what I think is the current record when they factored a 48-bit number with a quantum computer two years ago: https://arxiv.org/abs/2212.12372

I guess the news here is that now they've reached 22 bits using the quantum annealing technique which works on D-Wave's commercially-available quantum computers? That approach was previously able to factor an 18-bit number in 2018.

🥂 to the researchers, but 👎 to the clickbait headline writers. This is still nowhere near being a CRQC (cryptanalytically-relevant quantum computer).
