QUANTUM COMPUTING ENTERS FAULT-TOLERANT ERA AS SECURITY RISKS ACCELERATE
After decades of theory, quantum computing is moving toward real-world utility, with breakthroughs in error correction bringing both commercial opportunity and urgent cybersecurity risks closer to reality.
orrester has published a new
F report, The State of Quantum Computing, 2026, revealing that the timeline to quantum utility and‘ Q-Day’ has accelerated significantly.
As technology enters what the report describes as the‘ fault-tolerant foundation era’, quantum computing is moving from theoretical promise to real-world impact within the next five years, bringing both commercial opportunity and urgent cybersecurity implications.
In the long arc of technological progress, there are moments when possibility crystallises into inevitability. For quantum computing, 2025 marked that moment. After decades of theory, prototypes and overpromised timelines, the field crossed a critical threshold. The conversation is no longer about whether quantum computers will matter – but how soon they will begin to reshape industries, economies and security itself.
The report says 2026 is the year quantum computing entered its fault-tolerant foundation era.
The report says, the focus has shifted to logical qubits. www. intelligentcio. com
