纳米级粒子“量子挤压”首次实现 有助高精度传感与自动驾驶技术发展
Ke Ji Ri Bao· 2025-09-22 00:07
Core Insights - The research team from the University of Tokyo has achieved "quantum squeezing" of nanoscale particles, reducing their motion uncertainty below the quantum mechanical zero-point fluctuations, which opens new pathways for fundamental physics research and advances technologies like high-precision sensing, autonomous driving, and navigation without GPS signals [1][2]. Group 1 - The macroscopic physical world follows classical mechanics, while the microscopic world adheres to quantum mechanics, characterized by inherent uncertainty [1]. - Quantum squeezing refers to generating quantum states with uncertainty smaller than zero-point fluctuations, crucial for understanding natural phenomena and developing next-generation technologies influenced by quantum effects [1][2]. - The research team utilized glass-made nanoscale particles suspended in a vacuum and cooled to their lowest energy state to minimize uncertainty, successfully demonstrating quantum squeezing by achieving a narrower speed distribution than the lowest energy state [2]. Group 2 - The achievement of quantum squeezing was the result of overcoming numerous technical challenges over several years, including additional fluctuations from particle suspension and minor disturbances in the experimental environment [2]. - The suspended nanoscale particle system is highly sensitive to environmental changes, making it an ideal platform for studying the transition between quantum and classical mechanics, and laying the groundwork for the development of new quantum devices [2].

Core Idea - The book "The Logic of the World" by Professor Ma Zhaoyuan explores the evolution of human understanding of the world, emphasizing the impact of ancient Greek civilization, the nature of uncertainty in mathematics, and the implications of AI on human existence and reasoning [1]. Group 1: Influence of Ancient Greek Civilization - Ancient Greek civilization has a unique historical position, shaping the way humans understand the world and laying the foundation for philosophy, science, and art [12][14]. - The scientific spirit originating from ancient Greece encourages a courageous confrontation with ambiguity, viewing it as a motivation for further exploration [12][15]. - The development of a complete logical system in ancient Greece allowed knowledge to be accumulated and transmitted stably, which was crucial for the subsequent scientific revolution [16]. Group 2: Mathematical Crises and Uncertainty - The book discusses three crises in mathematics that shifted the focus from the pursuit of certainty to the acceptance of uncertainty [22]. - The first crisis relates to the Pythagorean crisis regarding irrational numbers, the second to the study of infinitesimals, and the third to set theory, particularly the foundational difficulties posed by Bertrand Russell [22][23]. - Gödel's incompleteness theorem is highlighted as a pivotal moment in human cognitive history, indicating that any finite, describable system is inherently flawed [23]. Group 3: AI and Modern Understanding - The rise of AI and the rediscovery of Bayesian statistics provide new methodologies that align more closely with human subjective cognitive processes [25]. - The book aims to explore the implications of Gödel's work on AI, deterministic computation, information theory, and chaos theory, revealing a new logical framework that challenges traditional notions of certainty [26]. - The interplay between uncertainty and modern scientific inquiry is presented as a profound and promising topic, reshaping our understanding of computation, information, and logic [26].

Core Insights - The core issue for companies today is not about finding opportunities but rather about standing firm amidst uncertainties brought by new technological revolutions like AI, big data, and cloud computing [1][2] Group 1: Uncertainties in New Technology Revolution - The uncertainties in the new technology revolution manifest in four main areas: 1. **Ambiguity in Technology Direction**: Companies struggle to identify which technological paths are viable due to rapid iterations and numerous options available [2][3] 2. **Jumping Market Demand**: Technology reshapes consumer needs abruptly, making traditional market research methods ineffective [4] 3. **Discrepancy in Organizational Capabilities**: Companies face challenges in aligning their existing workforce with new business models and technologies [5][6] 4. **Complex External Environment**: The interplay of technology with globalization, regulatory policies, and geopolitical factors adds layers of complexity to business operations [7][8] Group 2: Future Implications - The uncertainties will not lead to the elimination of companies but rather to the obsolescence of outdated thinking. Companies that can adapt to uncertainties will thrive, while those relying on past methodologies will struggle [9] - Three significant changes are anticipated: 1. **Agility Over Scale**: Smaller, faster companies may outperform larger ones due to their ability to quickly adapt and innovate [10] 2. **Resilience Over Efficiency**: Organizations must develop the ability to pivot quickly in response to changes rather than solely focusing on operational efficiency [11] 3. **Human Value Over Resources**: The ability to attract and retain talent capable of leveraging new technologies will become a core competitive advantage [12] Group 3: Strategies to Manage Uncertainty - Effective management of uncertainty involves enhancing organizational evolution capabilities rather than merely predicting future trends [13] - Recommended strategies include: 1. **Enhancing Digital Perception**: Companies should first understand the specific problems technology can solve before making investments [14][15] 2. **Building Flexible Organizations**: Smaller teams should be empowered to experiment and innovate, supported by a robust middle structure [16][17] 3. **Integrating Old and New Talent**: Combining the experience of older employees with the digital skills of new hires can create a synergistic effect [18] 4. **Cultivating a Culture of Learning**: Organizations should foster an environment where mistakes are viewed as learning opportunities rather than failures [19][20]
