For years, quantum computing promised to revolutionize everything from cryptography to drug discovery. But in 2026, where do we actually stand?

What's real:

  • IBM's 1,000+ qubit processors exist but error rates remain high
  • Hybrid classical-quantum algorithms show promise for optimization problems
  • Quantum annealing (D-Wave) works for specific use cases

What's still hype:

  • Breaking RSA encryption anytime soon
  • Replacing classical computers for everyday tasks
  • Affordable quantum computing for small businesses

Is quantum computing still 10+ years away from practical impact?
