In its Q2 2025 earnings call, IBM confirmed a major milestone: the deployment of IBM Quantum System Two in Japan, the first such system outside the United States. This isn’t just a milestone in hardware—it signals IBM’s intent to establish global leadership in quantum computing infrastructure. With fault-tolerant quantum computing still considered the “holy grail,” IBM has laid out a strategic roadmap targeting this breakthrough by 2029. As enterprise use cases multiply and quantum hardware and software stacks converge, IBM is aligning its innovation, partnerships, and execution to capture a first-mover advantage in a multi-billion-dollar future market.

But with rising capital costs, intensifying competition, and valuation headwinds, the road to quantum supremacy is anything but guaranteed. IBM’s recent deployment of its Quantum System Two in Japan, in collaboration with the RIKEN Institute, serves as a testament to its global ambition and strategic leadership in quantum computing. This system, IBM’s most advanced to date, symbolizes not only the company’s technological prowess but also its ability to secure government and academic collaborations in key international markets. The deployment reinforces IBM’s belief that quantum computing is not just a research initiative but a commercial imperative. The company is increasingly leaning into its decades-long R&D investments, combining proprietary quantum hardware with advanced control electronics, cryogenics, and software platforms. By integrating quantum into its broader enterprise stack—including watsonx, Red Hat OpenShift, and z17 infrastructure—IBM is crafting a vertically integrated play.

Unlike rivals focusing on point solutions or public cloud-based quantum experiments, IBM’s hybrid architecture allows enterprise clients to experiment, develop, and deploy quantum applications in controlled, secure environments. Its strategy leverages quantum computing as an extension of its core mission-critical IT systems, a key differentiator from cloud-native competitors. IBM’s use of client zero initiatives to scale its own quantum capabilities internally before external rollout further sets it apart. While Google’s Sycamore and Microsoft’s topological qubit theories garner media attention, IBM’s approach is grounded in execution, regulatory readiness, and practical use-case deployment. The Q2 2025 call also highlighted IBM’s resilience in navigating geopolitical uncertainties, regulatory frameworks, and constrained public sector spending—factors that could slow competitors. With over 70 workflows already powered by AI and automation tools developed in-house, IBM is setting the groundwork for integrating quantum into its enterprise AI and hybrid cloud solutions, creating a feedback loop of...

IBM’s target of achieving fault-tolerant quantum computing by 2029 reflects both ambition and strategic clarity. The roadmap is centered around a multi-layered stack: superconducting qubits for hardware, Qiskit for quantum software development, and middleware orchestration via watsonx and OpenShift. This layered strategy allows IBM to create synergies between its existing enterprise software and emerging quantum capabilities. Importantly, IBM is not merely chasing qubit count but focusing on quantum volume—a measure of computational power and reliability. In parallel, the company is developing error-correction protocols critical to realizing fault tolerance. IBM’s recent announcement of the Spyre Accelerator, set to become available in Q4 2025, is a pivotal step.

It will allow watsonx Code Assistant for Z and watsonx Assistant for Z to run natively on z17, effectively bringing quantum-ready AI applications into existing enterprise IT environments. IBM also launched Power11, advancing mission-critical workloads across hybrid environments, and tying that directly into its quantum narrative. By continuously upgrading core infrastructure like z17 and Power11 with AI and automation capabilities, IBM ensures the enterprise is quantum-ready even before the hardware is. This holistic integration provides IBM with a first-mover’s edge in building scalable, resilient, and AI-enhanced quantum systems. While rivals like Google chase theoretical quantum supremacy with high-risk, high-reward moonshots, IBM is building incrementally and pragmatically. The real test, however, will be in scaling its innovations beyond labs into revenue-generating, fault-tolerant solutions—a gap that no company has yet bridged.

IBM’s technological roadmap is credible but contingent on achieving major breakthroughs in quantum error correction, coherence time, and hardware scalability—all within a finite time horizon. IBM’s push toward quantum advantage is not happening in isolation. The company has aggressively expanded its global ecosystem to support the commercialization and scalability of its quantum strategy. Strategic collaborations with Oracle, Box, AWS, Salesforce, Microsoft, EY, and WPP highlight IBM’s ecosystem-first approach, embedding watsonx AI and eventually quantum tools into enterprise workflows. This strategy ensures that quantum computing, once viable, is not an experimental add-on but a core enabler of mission-critical business functions. IBM’s partnership with RIKEN in Japan to deploy Quantum System Two is particularly instructive—it demonstrates the company’s commitment to regional customization and regulatory alignment, which is crucial for government-led and academic quantum adoption.

On the software front, IBM’s embrace of open-source standards via Qiskit allows it to nurture a community of quantum developers, accelerating innovation and developer engagement without the lock-in concerns associated with competitors’ proprietary tools. Its recent acquisition of HashiCorp further adds infrastructure-as-code capabilities, enabling more automated and scalable deployment of quantum environments across hybrid architectures. Additionally, IBM’s client zero strategy—internally stress-testing quantum, AI, and hybrid cloud tools—provides a feedback loop for real-world validation before mass deployment. This approach minimizes go-to-market risk and enhances IBM’s credibility with enterprise clients who prioritize stability and regulatory compliance. With the GenAI book of business surpassing $7.5 billion and growing demand for hybrid cloud-AI integration, IBM is creating a fertile ground for quantum tools to piggyback on its existing commercial relationships. However, the success of this ecosystem hinges on sustained engagement, economic incentives for partners, and demonstrable client ROI—challenges that become magnified when dealing with a nascent and complex field like quantum computing.

IBM’s commitment to delivering fault-tolerant quantum computing by 2029 is ambitious and reflects long-term vision, but the execution risks are significant. Quantum computing remains a frontier technology with unresolved challenges, including qubit decoherence, error correction, and scalable hardware manufacturing. IBM’s credibility in execution stems from its consistent innovation cycle and its ability to commercialize new technology within its core enterprise base. However, even with the Quantum System Two deployment and roadmap clarity, the 2029 target carries inherent scientific, engineering, and commercial risks. Delays in quantum hardware development, talent acquisition, and regulatory compliance could impact the company’s ability to deliver. On the operational side, IBM has shown strength—free cash flow hit $4.8 billion in H1 2025, and the company raised its full-year FCF guidance to over $13.5 billion.

The z17 launch, with 67% year-over-year growth, and mainframe MIPS capacity expansion point to robust foundational infrastructure. But quantum computing is unlike traditional IT—development costs are higher, scaling is nonlinear, and returns may be delayed. Execution also depends on the successful integration of recent acquisitions like HashiCorp and DataStax, which, while strategically sound, add organizational complexity. Internally, IBM’s AI-driven productivity initiatives have driven over $3.5 billion in annual run-rate savings, a flywheel it hopes to replicate in quantum deployment. However, the stakes are higher here. Any misalignment between quantum R&D timelines and enterprise readiness could lead to investment misfires.

Moreover, IBM’s trailing valuation multiples—such as a 24.38x TEV/EBITDA and a 50.41x LTM P/E as of September 2025—suggest investor expectations are elevated. Any execution slippage could quickly compress these valuations, making precise delivery against roadmap milestones a non-negotiable.

Here’s how it works. IBM scientists say they have solved the biggest bottleneck in quantum computing and plan to launch the world's first large-scale, fault-tolerant machine by 2029. The new research demonstrates new error-correction techniques that the scientists say will lead to a system 20,000 times more powerful than any quantum computer in existence today. In two new studies uploaded June 2 and June 3 to the preprint arXiv server, the researchers revealed new error mitigation and correction techniques that sufficiently handle these errors and allow for the scaling... Half a century ago, a factory in Poughkeepsie, New York, cranked out computer hardware. The profits from mainframes financed pampered employees, scientific research and a dividend that made International Business Machines the most valuable company on the planet.

Now, a diminished IBM gets most of its revenue from soft things: computer programs and business services. But it’s at work on a new kind of machine that could return Poughkeepsie to its glory days. This is where it will assemble quantum computers, the magical devices designed to tackle mathematical challenges that would overwhelm an ordinary computer. If quantum delivers on its promises, engineers will use it to make giant strides in the design of drugs, vaccines, batteries and chemicals. Last year Boston Consulting Group predicted that come 2040, quantum hardware and software providers will be taking in $90 billion to $170 billion of annual revenue. IBM has been part of this rapidly evolving technology since the turn of the century.

Leading its effort: Jay Gambetta, a 46-year-old physicist from Australia who oversees 3,000 employees on six continents doing research. He will not stint quantum, since he has spent his entire career in that field. Gambetta joined IBM’s Watson Research Center, 39 miles south of the Poughkeepsie factory, in 2011 after postdoc years at Yale and then on the faculty at the University of Waterloo. He says, “While I like teaching, really I wanted to build.” June 10 2025 IBM made a landmark announcement outlining a clear path to build the world’s first large-scale, fault-tolerant quantum computer by the year 2029. Codenamed IBM Quantum “Starling,” this planned system will leverage a new scalable architecture to achieve on the order of 200 logical (error-corrected) qubits capable of executing 100 million quantum gates in a single computation.

IBM’s quantum leaders described this as “cracking the code to quantum error correction” – a breakthrough turning the long-held dream of useful quantum computing from fragile theory into an engineering reality. IBM used the occasion of quantum computing roadmap update to declare that it now has “the most viable path to realize fault-tolerant quantum computing” and is confident it will deliver a useful, large-scale quantum... The centerpiece of this plan is IBM Quantum Starling, a new processor and system architecture that IBM says will be constructed at its Poughkeepsie, NY facility – a site steeped in IBM computing history. Starling is slated to feature about 200 logical qubits (quantum bits protected by error correction) spread across a modular multi-chip system, rather than a single huge chip. According to IBM, Starling will be capable of running quantum circuits with 100 million quantum gate operations on those logical qubits. For context, that is orders of magnitude beyond what today’s noisy intermediate-scale quantum (NISQ) processors can reliably do.

IBM emphasizes that achieving this will mark the first practical, error-corrected quantum computer – a machine able to tackle real-world problems beyond the reach of classical supercomputers, thanks to its scale and reliability. A core theme of IBM’s announcement is the transition from today’s “fragile, monolithic” chip designs toward modular, scalable, error-corrected systems. Up to now, IBM (and most industry players) built quantum processors on single chips with qubits laid out in a planar array (IBM’s 127-qubit Eagle and 433-qubit Osprey chips are examples). These monolithic chips are limited in size and are not error-corrected – more qubits tend to introduce more noise. IBM’s new approach with Starling is modular quantum hardware: multiple smaller chips or modules will be interconnected via quantum links, allowing qubits in different modules to interact as if on one chip. IBM previewed this modular design with its IBM Quantum System Two infrastructure and experiments like the “Flamingo” coupler that demonstrated microwave links between chips.

By distributing qubits across replaceable modules connected quantumly, IBM can scale to much larger qubit counts than a single chip can support. Crucially, this modularity is paired with long-range entanglement – qubits on different chips can be entangled through couplers, overcoming the short-range connectivity limitations of a 2D chip lattice. IBM’s 2025 roadmap calls for a stepwise implementation of this modular architecture: for example, IBM Quantum “Loon” (expected in 2025) will test the new inter-chip couplers and other components, followed by Kookaburra (2026) to... All these lead up to Starling as the first full-scale fault-tolerant system in 2028–2029. In short, IBM is moving from building bigger single chips to building better systems of chips – a modular quantum compute unit that can be expanded piece by piece. Perhaps the most significant technical breakthrough underpinning IBM’s plan is its quantum error correction (QEC) scheme.
