Quantum computing is fast become one of the most talked-about emerging technologies. But for many enterprises, understanding lags far behind and an issue for another day. Bold predictions and technical complexities are intimidating for the average enterprise and is leading to a ‘we’ll deal with this when we need to’ attitude.
We included quantum computing as one of our top predicted technology trends for 2026 at the beginning of the year, but how is that playing out now we are a few months ahead? Should enterprises be paying close attention now to how the technology is progressing?
In this article, we look at some of the common misconceptions around quantum computing today and offer ideas on how to start thinking about it now to prepare for the future.
Quantum will replace classical computing
A common fear is that quantum computers will make today’s systems obsolete. In reality, quantum computing is not a replacement, it will complement what we know as normal computing.
Classical computers remain far better for everyday workloads like transaction processing, enterprise applications and data storage. Quantum systems are designed for very specific types of problems, such as complex optimization, cryptography and molecular simulation.
For enterprises, this means that in the future they will continue to rely on known infrastructure while selectively using quantum capabilities for targeted use.
It’s too early to take notice
Another widespread belief is that quantum computing is too far away to warrant any attention. This mindset overlooks the fact that preparation takes time and that enterprise technology environments are complex.
Cryptographic systems, data architectures and legacy applications cannot be transformed overnight, so waiting until quantum computing is fully mature would leave organizations vulnerable and rushing to catch up.
More importantly, hackers don’t always need to break your encryption today to cause damage later. They can collect and store encrypted data now, even if they can’t read it yet. When quantum computers become powerful enough, those same hackers could go back and unlock that old data. If your data needs to remain confidential for a decade or more, the risk already exists.
Only technology companies need to think about it
Quantum computing is often associated with large technology firms and research institutions, leading many organizations to assume it is irrelevant to their industry.
In reality, the impact will be broad. Industries such as finance, healthcare, pharmaceuticals, energy and logistics are likely to see early benefits and risks. Financial institutions could use quantum algorithms for advanced risk modelling, pharmaceutical companies for drug discovery and logistics firms to optimize complex supply chains.
Even organizations that never directly use quantum computing will be affected through competitors, partners and vendors. Ignoring it because you’re not a technology company could be a strategic blind spot.
There are no real use cases yet
It’s true that quantum computing has not yet delivered widespread commercial breakthroughs. But research and pilot projects are already underway in areas where classical computing struggles with scale and complexity. Areas such as optimization problems, materials science and advanced simulations.
The more important point is not whether quantum advantage exists today, but whether it could apply to their most complex problems in the future. Identifying those areas now allows organizations to experiment, learn and build internal expertise ahead of competitors.
We can wait until there are standards
Some organizations are delaying action until there are industry standards to adhere to. Understandable perhaps, but a risky approach, given perfect timing rarely exists in technology advances and early preparation is often the safer path.
Standards for quantum-resistant cryptography are already emerging and while they may yet evolve, the transition process itself will take years. Waiting for complete certainty could leave enterprises short on time to implement changes safely.
Data security is an immediate priority
In our new year predictions piece, we highlighted that enterprises need to be thinking now about quantum-resistant cryptography. Quantum computing threatens widely used encryption methods that protect everything from online transactions to internal communications. The solution is for organizations to start transitioning to quantum-resistant cryptography now.
Where do you start? Get a comprehensive understanding of where cryptographic methods are used across systems, where encryption can be embedded in applications, networks, devices and third-party services.
With full visibility, you can start to update cryptographic algorithms without rebuilding entire systems, but many legacy environments are not designed for this flexibility, making early planning essential.
Organizations should also start piloting quantum-resistant algorithms, particularly in lower-risk environments. A hybrid approach, combining traditional and quantum-resistant methods, can provide a practical bridge during the transition.
Finally, enterprise security can only ever be as secure as the supply chain, so engaging partners and vendors early on quantum-readiness should become part of procurement upfront in negotiations.
Getting ahead
Quantum computing is surrounded by both hype and hesitation, but neither extreme serves enterprises well. The reality lies in between. While transformative impact may still be years away, the groundwork needs to be laid now.
Quantum risk also requires a shift in how organizations think about data over time. The goal is not to predict exactly when quantum computing will arrive at scale, but to ensure that when it does, your business is prepared.
