Quantum Computing: What CEOs Should Know About the Next Revolution

Quantum computing is often touted as the next big technological leap forward – a revolution that could have far-reaching impacts on various industries, from medicine to finance.

However, while technology has the potential to solve complex problems beyond the reach of classical computers, it also raises questions and challenges that require strategic thinking. CEOs and executives must understand quantum computers’ fundamentals and transformative potential and assess when and how investments might make sense.

This article examines the key aspects of quantum computing, its opportunities and challenges, and its potential impact on various industries. CEOs gain strategic insights on preparing their companies for this technological revolution.

What is quantum computing, and how is it different from classical computers?

The key to understanding quantum computing lies in the principle of quantum mechanics.

Unlike classical computers, which are based on bits as the smallest unit of information and only operate in states 0 or 1, a quantum computer uses so-called qubits, which can simultaneously be in a state of 0, 1, or both – a so-called superposition. This property allows quantum computers to perform multiple calculations simultaneously and complete tasks exponentially faster than classical computers.

In addition, qubits can be connected via entanglement, which means that changing the state of one qubit has an immediate effect on others. This behavior offers enormous computational advantages because complex problems, such as those encountered in optimization, cryptography, and materials research, can potentially be solved more quickly.

What are the practical applications?

Although quantum computers are currently still in the development phase and large-scale applications will probably only become possible in the next few years, there are already initial application areas that CEOs should pay special attention to:

• Optimization and logistics: Quantum computers could tackle complex logistical challenges such as supply chain planning, route optimization, or inventory management. For example, German car manufacturer Volkswagen is testing quantum algorithms to optimize traffic flows to minimize congestion and increase efficiency in urban traffic.¹
• Pharmaceutical research and materials science: Quantum computers have the potential to accelerate the discovery of new drugs and materials by simulating molecular interactions that are too complex for classical computers. That could drastically reduce the time and cost of developing new drugs and enable revolutionary advances in materials development.
• Financial industry: Banks and investment firms see quantum computing as a way to analyze complex risk calculations and portfolio strategies more quickly and precisely. Goldman Sachs and JP Morgan are already investing in research initiatives to apply quantum computing in the financial sector to improve securities calculations and risk models.²
• Cybersecurity: One of the most revolutionary but riskiest applications of quantum computing involves cryptography. While quantum computers may be able to crack today’s encryption methods, the technology also opens up possibilities for quantum encryption, which is considered nearly unbreakable and could usher in a new era of data security.

Challenges and risks: Why CEOs should remain cautious

Despite its potential, quantum computing also comes with significant challenges. The technology (still) faces fundamental issues that must be overcome before widespread use becomes possible.

• Technological limitations and uncertainty: Quantum computers are extremely sensitive to external influences such as temperature and electromagnetic interference. Even minor deviations can cause malfunctions, and stable, scalable implementation in a production environment is not currently possible. These limitations mean that practical applications will likely remain limited to specialized niches over the next five to ten years.
• Cost and investment risk: Quantum computing is both technologically and economically challenging. Developing and maintaining a quantum computer requires significant investment, and companies should view the technology as a long-term, strategic project for now. The investment could take several years or even decades to pay off, increasing the risk for companies looking to invest in quantum computing at early stages.
• Legal and ethical issues: The possibility of overcoming current encryption standards raises security and ethical issues. Governments and companies are expected to prepare to develop new security standards for a world with quantum computers, which could create additional regulatory pressure.

How CEOs can act strategically

Quantum computing requires CEOs to weigh up the potential and risk carefully. Here are some strategic approaches to how leaders can prepare for this technological revolution:

• Promote education and awareness: Since quantum computing is highly complex, CEOs should regularly educate themselves and their leadership teams on progress and application areas. Working with research institutions and technology partners specializing in quantum computing can provide valuable insights.
• Support pilot projects and experiments: For CEOs willing to invest in the future, conducting pilot projects in collaboration with research institutes or technology providers can make sense. This way, the organization can gain experience with quantum computing without taking high risks.
• Enter into strategic partnerships: Since quantum computing is complex and resource-intensive, working with specialized companies or research institutes can make sense. Many large technology companies, such as IBM, Google, and Microsoft already offer quantum cloud solutions that allow companies to gain initial experience with the technology without developing their systems.³
• Develop proactive security strategies: Given the potential impact on cryptography, CEOs should learn about possible security strategies early on to be prepared if quantum computing threatens existing encryption technologies. Quantum-safe algorithms could play an essential role in the future.

Conclusion

Quantum computing has the potential to fundamentally change industries and solve problems that were previously considered unsolvable. While the technological and business opportunities appear enormous, companies must act realistically and with foresight.

CEOs should view quantum computing as a long-term investment that requires a mix of education, partnership, and strategic planning. Through pilot projects and collaborations, companies can prepare for this revolution early and make informed decisions to keep their company competitive in the long term.

The next few years will show how quickly the technology will mature. The key for CEOs remains to be informed and ready for the opportunities and challenges of quantum computing.
