Dear CIO,

Most of us have probably heard about Microsoft’s bombshell announcement on its new quantum chip that uses a new state of matter to function. In fact, recent announcements made by tech giants like Google and Microsoft have captured much of the industry’s attention. However, just like Rome, these quantum breakthroughs were not built in a day, and to truly understand whats going on, we need to take a step back and look at quantum as a whole. In today’s newsletter, I am going to give an in-depth look at the current state of quantum computing, the different strategies that each leading company is pursuing, as well as the legacy of research that companies like IBM have contributed over move than 40 years.

Navigating Immediate Breakthroughs and Long-Term Promise of Quantum Computing

Evidence and Reproducibility:
Google’s breakthrough in demonstrating quantum advantage with superconducting qubits last year was groundbreaking and thoroughly vetted by the scientific community. Independent, peer‐reviewed studies confirmed that their processors could perform certain computations far faster than classical systems. In contrast, Microsoft’s recent claims on achieving stable topological qubits rest on limited experimental data and robust theoretical models that have yet to see the same level of independent validation. This raises critical questions about whether Microsoft’s results can eventually withstand the rigorous reproducibility standards that have bolstered Google’s reputation. An important point is that most experts predict we are at least a decade away from achieving fully fault-tolerant universal quantum computers.

Experimental Validation:
While Google has delivered clear, reproducible demonstrations—often highlighted through tasks that significantly surpass classical computing—Microsoft’s strategy remains limited to controlled laboratory experiments and theoretical validation. The lack of scaled, application-specific demonstrations allows for skepticism about the maturity of Microsoft’s experimental methods.

Error Correction and Stability:
Microsoft is betting on topological qubits to provide a naturally resilient design against errors, utilizing exotic quasiparticles like Majorana zero modes. Theoretically, encoding quantum information in a system’s global topological properties should produce better error resistance. However, tangible performance metrics, such as coherence times and error rates, are still in the early stages of experimental validation. By comparison, Google’s superconducting qubits have well-documented error correction benchmarks shared and corroborated within the community. In simpler terms, imagine a system where the information is woven into the entire structure—like a carefully braided rope—so that the overall design remains intact even if part of it is disturbed. This contrasts with other designs where even a slight disturbance in a single component can lead to significant errors. While Microsoft’s approach is theoretically promising, researchers are still gathering experimental evidence to see if it can consistently perform under practical conditions.

Scalability and Commercial Viability:
Google’s processors have demonstrated incremental scalability with dozens of qubits and measurable quantum advantage in specific applications. In contrast, Microsoft faces significant engineering challenges—from maintaining ultra-low temperatures to requiring precise fabrication techniques—that must be addressed before its topological qubit systems can be effectively scaled to practical sizes. This issue is further complicated by the resource and cost implications of developing and sustaining such specialized systems. Additionally, while Microsoft expects commercialization within the next decade, Google’s ambitious milestones suggest a near-term roadmap already yielding practical, albeit niche, outcomes applications.

Strategic Focus and Broader Impact:
The two different paths Google and Microsoft take highlight a broader debate within the quantum ecosystem. Google’s application-driven focus seeks to capitalize on immediate quantum advantages, while Microsoft’s long-term, hardware-centered strategy focuses on developing fault-tolerant systems for the future. This isn’t just an arms race; it’s a complex innovation race. The fierce competition fuels cross-disciplinary research, engages academia, industry, and government entities alike, and lays the foundation for the next generation of quantum breakthroughs.

Despite the spotlight on recent breakthroughs, IBM’s long-standing commitment to quantum computing research reminds us of the field’s profound scientific roots. IBM’s journey began in the 1980s with foundational work in quantum information theory and has significantly evolved over the years. More than 40 years of theoretical exploration have culminated in a practical focus over the last decade, epitomized by initiatives like the IBM Q Experience. This enduring investment has advanced the science of quantum mechanics and created a stable platform for nurturing the quantum research ecosystem.

IBM’s ongoing research and development in quantum computing underscores an essential point for today’s CIOs: while enticing headlines may grab attention, lasting value comes from years of rigorous, foundational research. As the industry matures, blending immediate, application-specific successes with the deep, thorough research initiated by companies like IBM will be essential for advancing the quantum revolution.

Predicting the arrival of a fully fault-tolerant, universal quantum computer remains challenging. Experts generally agree that early prototypes designed for error correction and specialized tasks could emerge within the next 10 to 20 years, with broader and more versatile systems likely appearing in the mid-2030s or later. Until then, CIOs should regard current advancements in quantum computing as both a practical opportunity in niche areas and a long-term investment in a transformative technology still developing.

While Google and Microsoft push the envelope with aggressive, contrasting strategies, the quantum computing landscape rests on a solid foundation of decades of research—most notably from IBM. For CIOs assessing future technologies, it’s crucial to balance the attraction of immediate breakthroughs with the lasting, foundational work that supports long-term success in quantum computing computing.
