Group 1 - Japan's government has committed $7.4 billion (approximately 1.05 trillion yen) to quantum technology this year, which is more than three times the total investment over the past five years [1][2] - This investment represents a strategic shift driven by deep-seated concerns about historical failures in technology leadership, particularly in the semiconductor industry [3][4] - The Japanese government aims to transition from basic research to industrialization, with a clear goal of making quantum technology a pillar of future economic prosperity and national security [5][10] Group 2 - The investment is seen as a "preventive and high-risk" intervention to avoid being left behind in the global competition for technology leadership [7][9] - The government hopes to stimulate systemic change, encouraging research institutions, large enterprises, and potential startups to engage in the quantum race [8][9] - Japan's approach is characterized by a "collaborative giant ship" model, where the government leads and industrial giants collaborate, forming a powerful alliance [12][14] Group 3 - Major Japanese corporations like Toyota, NEC, and Fujitsu are expected to benefit significantly from government contracts and participation in core research projects [43][44] - The focus on building a self-sufficient supply chain for quantum technology components is a key aspect of Japan's strategy, aiming to avoid reliance on foreign suppliers [20][23] - The mixed quantum-classical computing strategy is seen as a pragmatic approach to leverage existing capabilities while aiming for quick results in various applications [17][18][19] Group 4 - Japan's commitment to quantum technology is likely to provoke responses from other major players, including the U.S. and China, potentially escalating a new round of "quantum arms race" [39][40][42] - The success of Japan's strategy will depend on overcoming challenges such as fostering a vibrant startup ecosystem and effectively translating research into marketable products [25][29][31] - Attracting and retaining top talent in the competitive global landscape is crucial for Japan to realize its quantum ambitions [32][34][38]
