Part 6/8:
Current estimations place the capabilities of today’s quantum computers—many a boastful 1,000 qubits—far below what's required to effectively conduct a long-range key recovery attack; forecasts suggest the demand could rise to between 13 million and 300 million qubits. Experts believe that even optimistic advancements in quantum computing are unlikely to overcome these barriers within the next decade, if ever at all.
Skepticism around the potential for practical quantum computing continues to grow, with discussions around error rates and operational coherence heightening the doubts on how close we are to achieving a working quantum computer that can launch such attacks.
