Quantum Computing: Separating Hype from Real-World Business Value
Lately, there has been a lot of talk about quantum computing, drawing interest from many, including business leaders. Quantum computing promises to solve previously unsolvable problems and revolutionize entire industries. As a result, excitement around its potential is rapidly growing. However, it is important to first ask where the hype ends and the real business value begins.
What is Quantum Computing?
Simply put, quantum computing is a new way of processing information. Unlike classical computers that use bits that are either 0 or 1, quantum computers use qubits (quantum bits). Qubits can exist in multiple states simultaneously as enabled by the principles of superposition and entanglement. This allows quantum computers to process vast amounts of information in parallel. Hence, quantum computers can theoretically tackle certain classes of problems that would take classical computers years to solve.
The Hype: Quantum’s Promised Revolution
Quantum computing is said to have the potential to perform tasks such as cracking encryption, revolutionizing drug discovery, optimizing global supply, and transforming artificial intelligence. Forecasts like one from Boston Consulting Group (BCG) project that quantum computing could unlock up to $850 billion in economic value by 2040. As a result, major industries are investing heavily and hoping to be among the first to benefit from a potential industrial revolution.
The Reality: Technical and Practical Challenges
The reality tells a different story. Today’s quantum hardware is still in its infancy, with most of these computers having fewer than 100 reliable qubits. They face issues such as noise and error rates that make large-scale practical applications elusive. Unlike classic chips that can be stacked for scaling needs, quantum systems can’t be easily scaled and need major advances in architecture and interconnects. Specialized expertise is also required to develop software for quantum machines. Besides, the algorithms that fully exploit the quantum advantage are still being researched. McKinsey estimates that while there may be many operational quantum computers by 2030, their ability to solve complex problems will take more time to mature.
This isn’t to say there is no hope as more improvement is made to quantum computing every day. Consider Google’s Willow, a 105-qubit processor introduced in December 2024. Willow addresses the error correction challenge and performs certain computations in under five minutes, which would take a supercomputer 10 septillion years.
Real-World Business Applications
Despite these challenges, quantum computing has demonstrated potential in real-world use cases. One example is Volkswagen who partnered with quantum computing firms to optimize traffic flow in Lisbon. This demonstrated how quantum algorithms can improve urban mobility. In finance, quantum-inspired algorithms are being tested for portfolio optimization and risk analysis by companies like JPMorgan Chase. Pharmaceutical companies are also testing molecular interactions with quantum simulation to potentially accelerate drug discovery. It’s worth noting that these applications are mainly hybrid solutions that use both quantum and classical computing. Even so, it signals there is potential in future breakthroughs.
Cloud-based quantum computing availed by platforms like IBM, Microsoft and Google have greatly contributed to this venture. These resources have made experimentation possible without the need for in-house quantum hardware. Therefore, businesses have a chance to innovate solutions to complex problems more affordably.
An example of a strategic framework that can help business leaders is the “quantum economic advantage” developed by MIT and Accenture. It requires two conditions: a quantum computer capable of handling the problem’s size (feasibility) and a quantum algorithm that outperforms a similarly priced classical solution (algorithmic advantage). Only when both conditions are met does quantum computing become economically beneficial.
How Businesses Should Get Ready for Quantum Computing
Preparing for quantum computing doesn’t require immediate transformation; however, it does call for strategic foresight. Here’s how businesses can begin laying the groundwork today.
- Create a Quantum Strategy: Identify potential long-term use cases where quantum could offer an edge, and develop a roadmap aligned with industry trends and business goals.
- Invest in Collaboration and Research: Partner with universities, quantum startups, and industry groups to stay updated and explore early-stage innovations.
- Start Quantum-Proofing Security: Begin evaluating quantum-resistant encryption methods to safeguard future data as quantum threats to cybersecurity emerge.
- Experiment Safely: Use cloud-based quantum platforms to run small pilots or simulations, gaining hands-on experience without major commitments.
- Build Internal Capability: Upskill current staff in foundational quantum concepts to ensure your team can engage with this evolving technology when the time is right.
Final Thoughts
Quantum computing is in its early stages, but its disruptive potential and rapid development give businesses a reason to start planning on its adoption, or risk falling behind. Integrating quantum has the potential to boost efficiency, cut costs, and enable innovative products and services. To stay competitive, businesses should start building a quantum-ready workforce through training, hiring, and academic partnerships.
