Every few years, quantum computing experiences a media cycle that oscillates between breathless hype and dismissive skepticism. We are currently in one of those cycles, and it is more consequential than previous ones because the underlying technology has genuinely advanced.
Let me try to give you a sober assessment of where we actually are.
What Has Actually Changed
The honest answer is that quantum hardware has improved substantially, but the gap between current capabilities and commercially useful quantum advantage remains significant. The leading quantum computers today — from IBM, Google, and a handful of well-funded startups — can perform certain calculations that would be impractical on classical hardware. But "impractical on classical hardware" is not the same as "commercially valuable."
The key metric to watch is not qubit count — which is what most press coverage focuses on — but error rates and coherence times. A quantum computer with 1,000 noisy qubits is far less useful than one with 100 highly reliable ones. The field is making progress on error correction, but fault-tolerant quantum computing at scale remains years away.
What This Means for Technology Leaders
The appropriate response to quantum computing depends entirely on your industry and your specific risk profile.
For most organizations, the relevant near-term concern is cryptographic risk. Current public-key cryptography — the foundation of most internet security — is theoretically vulnerable to sufficiently powerful quantum computers. "Harvest now, decrypt later" attacks, where adversaries collect encrypted data today to decrypt when quantum computers become capable, are a real concern for any organization handling data with long-term sensitivity.
The practical response is to begin cryptographic agility: auditing your systems for quantum-vulnerable cryptography and developing a migration plan to post-quantum standards. NIST finalized its first post-quantum cryptographic standards in 2024, and implementation should be on every CISO's roadmap.
The Opportunity Side
Beyond cryptographic risk, quantum computing offers genuine long-term opportunity in specific domains: drug discovery, materials science, financial optimization, and logistics. If your organization operates in these areas, now is the time to build quantum literacy — not to deploy quantum solutions, but to understand the landscape well enough to recognize when genuine advantage becomes available.
The organizations that will capture quantum advantage first are those that have been building understanding and relationships in the quantum ecosystem for years before practical advantage arrives.
