   @hipsterelectron @foolishowl @dalias @Ember I'll caution that it does seem to exist and it is apparently already proven to break things, but the key sizes it can work with are as-yet tiny (the example in thinking of was only a 50-bit key RSA)

   The barrier is scale-up, and I think assuming that can't ever happen is dangerous.

   Here's the report I'm thinking of. I don't speak or read Chinese so I can't read the paper for myself: https://www.livescience.com/technology/computing/chinese-scientists-claim-they-broke-rsa-encryption-with-a-quantum-computer-but-theres-a-catch

   Here's the paper though, to save a click if someone wants to try to read it: http://cjc.ict.ac.cn/online/onlinepaper/wc-202458160402.pdf
