June 10, 2025 IBM has committed to building the world’s first fault-tolerant quantum computer by 2029, marking a decisive step in moving the field from experimental breakthroughs to commercial-scale deployment. The announcement lays down a public timeline from a company with global credibility and enterprise reach.
The system IBM is aiming to build won’t just run quantum code — it will correct errors in real time, a critical requirement for sustained and reliable operation. Today’s quantum computers are notoriously fragile, with qubits prone to decoherence from even minor interference. Fault tolerance means those errors could be mitigated as part of regular computation, unlocking real-world applications across materials science, logistics, and cryptography.
“By 2029, we aim to have a quantum system that can run an error-corrected, fault-tolerant algorithm — and do so faster than a classical computer,” IBM stated in its updated development roadmap released this week.

IBM has played a steady hand in quantum while watching its early lead in artificial intelligence fade as companies like OpenAI and Google surged ahead. The quantum announcement signals IBM’s determination not to repeat that mistake.
The move doesn’t overshadow the advances made by other global players — or those in Canada. Montreal-based Nord Quantique has attracted attention for its work on hardware-efficient error correction. Toronto’s Xanadu continues development on photonic quantum processors, and B.C.-based D-Wave remains a pioneer in quantum annealing systems. But IBM’s declaration sets a commercial target — and puts pressure on others to match it.
While 2029 is still years away, a defined deadline from a company like IBM shifts the conversation from possibility to planning. Quantum is no longer just a science project — it’s entering the enterprise roadmap.
