Thanks for this great article. I can't stop laughing. Yesterday, I was completely puzzled by Terra Quantum's claims, their press release was written in an extremely confident tone and it almost fooled me (I didn't realize they "worked on" on MD5 or Quantum Demon...). > the company said its research found that even the strongest versions of AES encryption may be decipherable by quantum computers that could be available in a few years from now. Everyone knows 256-bit symmetric ciphers in general are post-quantum secure, I had a discussion a week ago (and someone also reminded me about the caveat of block size, the blog author also commented [0]). Then, yesterday the news hype sounded like they've discovered an efficient quantum algorithm to attack the internal structure of AES, and it can break even AES-256 (despite 20 years of research in post-quantum cryptography, nobody found one). I said "big if true..." when I read it. Unsurprisingly, it turned out that it isn't just not true, but not even wrong. The company doesn't even understand the basic of cryptography.
