Introduction. Quantum mechanics, the most important discovery of physics in the 20th century, reveals the curious laws of the microscopic world. However, with the further development of quantum mechanics, the debate about its completeness and localized realism has become more and more intense. To resolve this controversy, Bell's inequality and the subsequent Bell experiment became key. This article will lead readers into this wonderful journey of exploring the quantum world through the Big Bell experiment and its scientific significance.
1. The controversy of quantum mechanics and the proposal of Bell's inequality.
Localized realism holds that the state of a physical system exists objectively and has nothing to do with the observer's choice. However, the phenomenon of quantum entanglement seems to violate this principle, as two entangled quantum systems depend on each other in their states, even if they are far apart. Einstein et al. thus proposed the famous EPR paradox, arguing that quantum mechanics is an incomplete theory.
To solve this problem, Bell proposed Bell's inequality in 1964. It gives a way to experimentally test the difference between quantum mechanics and localized realism. If the state of a physical system is determined by latent variables, then their correlation should satisfy certain limits; And if the state of a physical system is described by quantum mechanics, then their correlation should exceed these limits. Thus, by measuring the correlation of physical systems, we can tell whether physical systems obey Bell's inequality and thus whether they obey localized realism or quantum mechanics.
2. The implementation of the Bell experiment and the Big Bell experiment.
To verify Bell's inequality, scientists conducted a series of Bell experiments. These experiments often make use of quantum entanglement, such as two entangled photons or electrons, to measure their correlation. The experimental results show that Bell's inequality is violated, supporting the completeness of quantum mechanics.
However, there are also some problems and loopholes in these experiments, such as the efficiency, fairness, and freedom of the experiments. In order to solve these problems and loopholes, the Big Bell experiment came into being. The Big Bell Experiment mobilized volunteers across the globe to generate random numbers and conduct experiments using different quantum systems and labs. The purpose of this experiment is to verify the correctness of quantum mechanics and close possible loopholes.
In the Big Bell experiment, a large number of random numbers were first generated through the ** game "Big Bell Test". These random numbers are assigned to different laboratories and quantum systems to determine how each quantum system is observed. The labs and quantum systems then measured the correlation between the two entangled quantum systems to see if Bell's inequality was violated. Finally, the results and analyses of these experiments were summarized to draw clear conclusions.
3. The significance and future prospects of the Big Bell experiment.
The results of the Big Bell experiment once again prove the completeness of quantum mechanics and exclude the possibility of localized realism and hidden variables. This experiment not only provides us with a deeper understanding of the quantum world, but also demonstrates the important role of human free will in scientific experiments.
However, the Big Bell experiment is not the end, but a new beginning. It provides us with a broader field of study and a deeper space for thinking. Future research can further explore the nature of quantum entanglement, the application prospects of quantum mechanics, and interdisciplinary research with other fields.
Conclusion. The Big Bell experiment is an amazing journey into the quantum world. It not only verifies the completeness of quantum mechanics, but also demonstrates the important role of human free will in scientific experiments. Through this experiment, we have a deeper understanding of the quantum world and a broader space for future research. Let's continue this amazing journey of discovery and uncover more mysteries of the quantum world!
