Quantum Computing: Still a Long Road Ahead—Cautious Outlooks from IT Giants
Quantum Computing: A Paradigm Shift in Modern IT
Quantum computing has drawn significant attention as an innovative concept poised to transform the paradigm of modern IT. However, there are still numerous challenges to overcome before it becomes fully commercialized. Recently, several major IT figures have shared cautious outlooks on the technology, sparking lively discussions on the pace of development and realistic applications.
In particular, the potential impact of quantum computing on fields such as artificial intelligence and data analytics has garnered considerable interest. Nonetheless, experts emphasize the need for a careful approach due to the complexity and uncertainty of this technology. At this juncture, it is critically important to examine the current state of quantum computing and its future directions.
Current State of Quantum Computing
Quantum computers are still in the early stages of commercialization, with significant technical hurdles and limitations remaining. Maintaining quantum states and measuring them accurately pose substantial challenges, and superconducting technology—requiring extremely low temperatures—remains essential. These technical difficulties are among the main obstacles preventing quantum computers from being fully practical.
Several big tech companies, including Google, IBM, Amazon, and Microsoft, are actively working on quantum computer development, though each has its own distinct strategy. Google, for example, aims to commercialize quantum computers by 2031 and is focusing on developing quantum algorithms for stable implementations. Despite these efforts, quantum computers currently excel only in solving specific problems, falling short in terms of general-purpose functionality.
Additionally, comparing the performance of quantum computers with traditional computers remains challenging. While quantum computers may outperform classical computers in certain domains, high error rates often undermine their practicality. This reality suggests that quantum computing still has a long way to go before achieving widespread commercialization.

Many companies are enthusiastically investing in quantum computing research. For instance, IBM plans to commercialize a quantum processor with more than 1,200 qubits by 2025 and invests roughly USD 1 billion each year toward this goal. These efforts aim to improve hardware performance and establish a robust quantum software ecosystem.
Despite these ambitions, major IT players continue to advocate for a cautious approach to commercializing quantum computing. Rushing the process could lead to various complications, and opinions about success rates differ widely. Google, for example, is conducting research based on its quantum chip “Willow,” although many challenges remain unresolved.
As quantum computing technology advances, hardware performance is expected to double every one to two years, and the development of new quantum algorithms holds great promise. Such breakthroughs could drive innovation in finance, pharmaceutical research, cryptography, and other fields. However, due to low fidelity levels, mass adoption will likely require more time. Classical computing technologies also continue to evolve, indicating that the road to quantum computing commercialization will be a lengthy one.
Future Outlook and Challenges

Research on quantum algorithms is a crucial factor in determining the future of quantum computing. Although large corporations like IBM, Google, and Microsoft are experimenting with quantum algorithms, numerous technical barriers must still be overcome before they can be applied to real-world industrial problems. Without further advancements in these algorithms, the commercialization of quantum computers will remain difficult.
Security and privacy issues are emerging as particularly critical concerns in quantum computing. When handling sensitive information, guaranteeing data safety and integrity is paramount. Currently, many researchers are investigating quantum delegated computing models to protect clients’ sensitive information, but a complete solution has yet to be found.
It is widely anticipated that significant time will be needed before we see fully realized industrial use cases. While various industries—including finance, healthcare, and logistics—are exploring the potential of quantum computing, additional research and development are essential for genuine problem-solving applications. In finance, for example, quantum computers could enhance risk analysis, but fully implementing such solutions will require considerably more time.
Corporate Strategies Based on Outlook

Companies are investing in quantum computing research with measured caution. IBM, for instance, allocates about USD 1 billion annually and is expected to reach a cumulative investment of roughly USD 5 billion by 2024. This hefty expenditure underscores the fact that businesses recognize the potential of quantum computing.
Partnerships and collaborations are also key strategies to accelerate technological progress. The partnership between Q-CTRL and OQC, for example, aims to tackle complex problems that quantum developers and enterprises struggle with, as well as improve algorithm performance. Such collaborative approaches are vital for advancing quantum computing.
A clear corporate strategy is needed to harness the potential of quantum computing. Its applications can extend to AI, drug development, finance, national defense, aerospace, and more—opening up new opportunities. Consequently, companies must adopt a strategic approach to maximize these possibilities.
The Future of Quantum Computing: Cautious Optimism and Preparation
Despite high expectations for quantum computing, many challenges remain. As evidenced by the careful projections of IT giants, technological progress requires time, along with continued preparation and research. Our future may hinge on our ability to benefit from the innovations quantum computing can bring.
Now is the time to monitor the evolution of quantum computing and consider how these changes will shape our daily lives. To seize the new opportunities made possible by technological advancement, we must stay informed and expand our knowledge. By accompanying quantum computing on its journey, we can better prepare for what lies ahead.
