Quantum computing has long been surrounded by hype, research papers, and futuristic promises. But beyond the theory lies a world of real, tangible opportunities. For industries such as manufacturing, healthcare, energy, and telecommunications, quantum technologies could solve business challenges faster and more cost-effectively than ever before. At the same time, the rise of quantum also poses new risks, particularly to encryption systems that currently secure sensitive data. Recognizing both the potential and the risks is essential for businesses preparing for the next wave of technological transformation.

Why Do We Need Quantum Computing?
Despite enormous advances in classical computing, certain problems remain unsolved. For instance, creating a room-temperature superconductor could revolutionize global energy systems, yet classical computers struggle to simulate the complex interactions of quantum particles. Similarly, medical research is limited because traditional computers cannot accurately model large molecules.
Even in optimization and machine learning, industries often hit barriers due to limited computing resources. Quantum computers, with their fundamentally different computing paradigm, are designed to handle such problems by simulating nature itself. This opens possibilities for breakthroughs in medicine, energy, logistics, and beyond.
How Quantum Computing Impacts Industries
Today’s devices fall under the Noisy Intermediate Scale Quantum (NISQ) era, meaning they operate with a few hundred qubits and remain error-prone. Yet, even these early machines show promise when paired with classical systems through Variational Quantum Algorithms (VQAs).
Industries stand to benefit in areas such as:
- Optimization: Enhancing telecom networks, supply chains, logistics, and manufacturing workflows.
- Machine Learning: Detecting anomalies to identify defects in production.
- Fluid Dynamics: Simulating airflow to design more aerodynamic vehicles.
The long-term ambition is a universal, error-corrected quantum computer capable of running any algorithm. Such a system could unlock new materials for clean energy, advanced batteries, and even room-temperature superconductors—transforming industries and accelerating solutions to climate change.
Industries Poised for Early Benefits
Sectors with complex supply chains are expected to see the first wave of quantum-driven advantages. Companies in energy, construction, transportation, aerospace, materials science, telecom, and manufacturing are already exploring applications.
For example:
- Quantum models are being applied to develop next-generation batteries.
- The aerospace industry is experimenting with digital twins powered by quantum fluid simulations.
- Advanced manufacturers are testing quantum solutions for supply chain optimization and fault detection.
These practical applications could deliver fast and measurable returns, giving early adopters a significant competitive edge.
Quantum as an Economic Opportunity
The rise of quantum computing is more than a scientific breakthrough—it represents a vast economic ecosystem. Companies won’t just buy access to quantum computers; they will invest in a complete value chain:
- Consultancy services to identify quantum-ready problems.
- Quantum software and algorithms tailored to specific industries.
- Specialized hardware components, including refrigeration systems, lasers, and semiconductor designs.
Each layer of this ecosystem generates opportunities for innovation, growth, and collaboration across industries.
What Exactly Is a Quantum Computer?
Unlike traditional computers that rely on bits representing 0 or 1, quantum computers use qubits. Thanks to quantum mechanics, qubits can exist in a superposition, meaning they represent both 0 and 1 simultaneously.
This property, combined with entanglement—where qubits share information regardless of distance—enables massive parallel processing. The result is computational power far beyond what classical systems can achieve for specific problems.
How Is Quantum Different from Classical Computing?
In classical systems, computations happen sequentially, limited by binary states. Quantum computing, however, leverages superposition and entanglement to explore multiple outcomes at once. This parallelism offers exponential advantages in fields like cryptography, optimization, and material science.
Understanding Quantum Supremacy
In 2019, Google announced it had achieved quantum supremacy when its 53-qubit processor performed a calculation deemed impossible for classical computers. While the specific task had little real-world use and was prone to error, the demonstration signaled that quantum advantage—where quantum systems outperform classical ones in business contexts—is within reach.
When Will Quantum Computing Become Commercially Viable?
Experts predict commercial viability within three to eight years for specific applications, while universal fault-tolerant machines may take at least a decade. Yet even now, some companies use quantum-inspired algorithms to optimize processes and gain operational insights. In other words, the impact is already beginning.
Who Will Have Access to Quantum Systems?
Quantum computing is no longer limited to elite research labs. Platforms like IBM Qiskit, Amazon Braket, and Microsoft Azure Quantum allow developers worldwide to experiment with quantum devices via the cloud. Hardware vendors such as D-Wave also provide commercial access, while innovation hubs like Digital Catapult run programs to help businesses explore practical applications.
The UK’s Role in Quantum Development
The UK has positioned itself as a major player in the global quantum race. Since 2014, the country has invested over £1 billion in quantum research and recently committed £2.5 billion through its National Quantum Strategy.
The National Quantum Computing Centre (NQCC) reports the UK ranks fourth in program delivery and second in commercialization globally. Companies like Oxford Quantum Circuits, Orca, Phasecraft, and Riverlane are pioneering hardware and software innovations, while Quantinuum—a merger of Cambridge Quantum and Honeywell—leads internationally in integrated solutions.
Potential Risks and Negative Consequences
Like artificial intelligence, quantum technology carries risks. One major concern is encryption. Shor’s algorithm, developed in 1994, demonstrated that quantum computers could eventually break RSA encryption, the standard securing much of today’s digital infrastructure.
Although fully fault-tolerant quantum computers may be decades away, “store now, break later” attacks pose an immediate risk. Hackers could store encrypted data today and decrypt it once powerful enough machines emerge.
Building Quantum-Safe Systems
To safeguard against these risks, industries must begin transitioning to quantum-safe encryption strategies. This involves updating both software and hardware to withstand quantum-based attacks. Much like the adoption of the internet or the silicon chip, the transition will take time—but preparation is essential.
