This article is meant to be a short, well sourced summary about why we will not have quantum computing any time soon, with evidence that shows we have not made any meaningful progress for decades, at least nowhere near the level the PR lies from the tech industry would have led you to believe.

• The actual challenges for quantum computing
  • Decoherence time
  • Gate fidelity
  • Error correction
• The current landscape
  • The only real qubit “computation” that has ever been done
  • But I thought bigger numbers have been factored?
  • Misleading and meaningless “benchmarks”
  • What about the new types of qubits?
  • Claims of “improved algorithms”
  • Large scale manufacturing of “Quantum hardware”
• Scale of requirements for a real, useful quantum computer
• Conclusion
