    Quantum computers are specialists, not general replacements.
    What tasks do you think they’re BEST suited for?

    • Sven replied 6 months ago
      Definitely cryptography. Once large-scale machines are stable, RSA won’t stand a chance.
        • Good point, Sven! Especially with algorithms like Peter Shor’s factoring method 👀
          But do you think breaking encryption will happen soon — or are we still far from that scale?
        • Lars replied 6 months ago
          Drug discovery and molecular simulation. That’s where quantum advantage seems most practical.

          Myth or Fact?
          “Quantum computers will replace classical computers soon.”
          👉 Drop MYTH or FACT and explain why.

          • MYTH. Quantum computers are not general-purpose replacements. They’re built for very specific problems like optimization or cryptography.
              • Adding to this — even companies like IBM and Google position quantum systems as complementary to classical systems, not replacements.
                  • Sven, Yes! Hybrid computing is the direction most researchers are pushing — classical + quantum working together.
                  • Great point, Lars! 🙌 Exactly — quantum computers excel in niche tasks but can’t run your spreadsheets or social media apps (yet!)
                • I love how the unicorn is “what I say” and the conspiracy theorist is “what they hear” 😂
