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.

      I’m sure he is joking. For example the lowest key size openssl supports is 512 bits and this is really small. Anything below 1024 bits has been considered insecure for a while now. Typical RSA key length is 2048. For a 22 bit RSA key you don’t need a quantum computer, this is so small a laptop CPU can break this in a short time. As with EC crypto: this won’t save you from quantum computer attacks, in fact a typical 256 bit EC key needs less qbits to be broken (1500) then 2048 bit RSA(4096).
