Quantum computing is no longer a distant promise and your business should start paying attention

For years, quantum computing occupied a peculiar space in the business conversation. It was simultaneously regarded as the most important technology of the coming decades and as something perpetually five to ten years away from practical relevance. In 2026, that framing has started to break down. Quantum computing has not yet delivered the full-scale, fault-tolerant capabilities that would transform every industry overnight — but it has moved decisively from laboratory curiosity to a technology that business leaders in every major sector need to actively monitor and begin preparing for.

McKinsey's 2026 Quantum Technology Monitor, described by analysts as a commercial tipping point, documents over 300 organizations including Airbus, Boehringer Ingelheim, JPMorgan Chase, and Liberty Mutual actively collaborating with quantum computing companies on real business challenges. Early movers are transitioning from isolated pilots to applications embedded in end-to-end workflows. The global market for quantum computing generated more than $1 billion in revenue in 2025, with projections suggesting it could reach $4.4 billion by 2028. And across industries, McKinsey estimates that quantum computing could unlock up to $2.7 trillion in economic value by 2035.

What quantum computing actually does

The key to understanding quantum computing's business relevance is understanding which problems it solves well. Unlike classical computers, which process information as binary ones and zeroes, quantum computers use quantum bits — qubits — that can exist in multiple states simultaneously, a property called superposition. Combined with entanglement (where qubits become correlated in ways that classical physics cannot replicate), this allows quantum computers to explore enormous solution spaces in parallel rather than sequentially.

This architecture is not universally better than classical computing — most of what runs on a laptop is unlikely to benefit from quantum hardware. But there is a class of problems where quantum mechanics provides a genuine computational shortcut: molecular and chemical simulations, certain optimization problems, cryptography, and pattern recognition in very high-dimensional datasets. For industries where even marginal improvements in these areas translate to enormous value, this matters enormously.

In chemicals and life sciences, companies are using quantum simulation to run molecular-level experiments that classical computers cannot feasibly model. Drug discovery, which typically takes more than a decade and billions of dollars to move a single treatment from concept to clinic, is one of the most compelling near-term applications. Quantum systems simulate protein interactions and molecular behavior in the same mathematical language as the underlying physics — making them a natural fit for the problem in a way classical systems are not.

In finance, portfolio optimization and risk modeling involve the kind of high-dimensional probability calculations where quantum advantage is credible. JPMorgan Chase has been actively exploring quantum-accelerated risk engines, and several major financial institutions have quantum computing teams working toward embedded workflow applications. In logistics and manufacturing, routing and scheduling optimization — problems that become exponentially harder as networks grow — are natural candidates for hybrid quantum-classical approaches.

The encryption threat you cannot ignore

One aspect of quantum computing that demands immediate attention from every business — not just those in sectors with obvious quantum applications — is the threat it poses to current encryption standards.

RSA and elliptic curve cryptography, the mathematical foundations securing most digital communications, derive their security from problems that are computationally intractable for classical computers. Quantum computers running Shor's algorithm can theoretically solve these problems efficiently. The required hardware scale has been revised downward significantly in recent research, with some 2026 estimates suggesting RSA-2048 could be broken with fewer than 100,000 physical qubits under specific conditions — far fewer than earlier estimates of millions of qubits. These are theoretical proposals rather than demonstrated capabilities, and current quantum hardware operates at scales far below what would be required. But the timeline for when this becomes a real threat is no longer certain.

This creates what security experts call the harvest-now-decrypt-later risk. Adversaries may already be collecting encrypted data with the intention of decrypting it once quantum hardware reaches sufficient scale. For organizations handling information that must remain confidential into the 2030s — healthcare records, legal documents, financial transactions, government communications — that risk is relevant today, not in some distant future. The transition to post-quantum cryptographic standards, which NIST finalized in 2024, is something organizations should be actively planning regardless of where they stand on quantum computing as an opportunity.

How to think about quantum strategy right now

The business case for engaging with quantum computing in 2026 does not require betting on a specific timeline for fault-tolerant quantum hardware, which most analysts now expect around 2030. It requires honest assessment of where your organization sits in the landscape of potential beneficiaries and what the cost of being unprepared looks like.

Cloud-based quantum access through platforms like IBM Quantum, Amazon Braket, and Google Quantum AI has made experimentation accessible at a fraction of the cost of owning quantum hardware. Organizations can identify high-value workloads — typically involving complex optimization, molecular simulation, or cryptographic risk — and begin structured pilots using quantum-as-a-service offerings without major capital commitment.

The organizations that will capture the $2.7 trillion McKinsey estimates in quantum value over the next decade will not be those that waited for definitive proof of commercial readiness. They will be those building quantum literacy, talent, and experimental workflows now — so that when fault-tolerant hardware arrives, they are positioned to deploy it at scale rather than starting from scratch.
