The signs of a technology in breakthrough mode are everywhere. Google cracked a 30-year error barrier. Microsoft built a new type of qubit. IBM revealed its Nighthawk processor and a roadmap to the world’s first large-scale fault-tolerant quantum computer. Meanwhile, pure-play quantum stocks posted gains of hundreds — in some cases thousands — of percent over the past year, as investors poured somewhere between $4 billion and $5 billion into quantum startups.
And yet, an uncomfortable truth lingers just beneath the surface of the excitement: Quantum computers have produced extraordinary benchmark results and a handful of promising early-stage commercial demonstrations but nothing that is commercially indispensable. The field sits in a strange and liminal place: something is happening but equally clearly, the revolution is not here yet.
This is the quantum paradox of 2026. The breakthroughs are real. The timelines are real. And the gap between today’s machines and the fault-tolerant quantum computers needed to unlock transformational applications is also very real.
“Why Quantum Is Around The Corner And Why It Is Not” was the title of a panel moderated by The Innovator’s Editor-in-Chief at the World Economic Forum’s annual meeting in Davos. Panelists included IBM Chairman Arvind Grishna, Lene Oddershede, Chief Scientific Officer, Planetary Science and Technology, Novo Nordisk Foundation, Doreen Bogdan-Martin, Secretary General of the International Telecommunications Union, and 2025 Nobel Prize Laureate in Physics John Martinis (see The Innovator’s separate interview with Martinis)
This story builds on that conversation and looks at the breakthroughs and barriers of quantum computing, a technology that promises to optimize business operations through advanced machine learning and simulations, improve the accuracy of disease detection, and ensure secure data transmission with cutting-edge encryption, which is crucial for future-proofing cybersecurity.
