A Chinese Folk Scientist-From the Financial Market to Quantum Many-Body Theory
Published in Physics, Computational Sciences, and Mathematics
Mr. Leilei Shi was born in Jinhua, Zhejiang Province, China, in 1959. He is the youngest of five children and grew up with four sisters. His father, Anju Shi, born in Tongliang, Chongqing, in 1911, was a pediatrician, while his mother, Suhua Liao, born in Xiluo, Taiwan Province, in 1922, worked as a maternity assistant at a hospital. Mr. Shi currently resides permanently in Beijing, P.R. China. He got married at the age of 50, retired at 60 in 2019, and continued working at Haitong Securities Co., Ltd. (Guotai Haitong) until 2024. He is now a father to a 13-year-old son.
In 2024, Mr. Shi founded Beijing Shangdafei Science & Technology Co., Ltd., which focuses on various high-tech areas, including quantum information technology, artificial general intelligence (AGI), and wireless AGI entanglement communications (7G wireless communications).
Mr. Shi obtained a Bachelor of Science in physics from the University of Science and Technology of China (USTC) in Hefei in 1982. He later pursued studies in business management at the Asian Institute of Management (AIM) in the Philippines, supported by a scholarship from the Asian Development Bank — The Government of Japan during the 1992-1993 academic year. In 2006, he made a significant discovery in the financial markets, unveiling a cumulative trading volume-price probability wave equation [1-5]. Since 2018, he has served as an industry advisor for the Master's in Finance Program at the School of Management at USTC, a three-year, full-time program.
Inspired by the nonlocal many-agent trading wave equation in financial markets, Mr. Shi led a research group that authored the paper entitled "Interaction Wave Functions for Interaction-Based Coherence and Entanglement in Complex Adaptive Systems.” This paper was published online in the International Journal of Theoretical Physics on November 17, 2025 [6]. The authors proposed a new framework to uncover the underlying mechanism of interaction-coherent entanglement. This concept has puzzled the scientific community for over 90 years since the introduction of the Einstein-Podolsky-Rosen (EPR) paradox in 1935 [7].
As a freshman in the Department of Physics at USTC in 1978, Mr. Shi was profoundly influenced by a mechanics course taught by senior lecturer Mr. Li-Zhi Fang (see Fig. 1). Mr. Fang encouraged students to treat many-body problems as complex systems by using a "black box" approach, rather than solely relying on Newton's laws. He advised students to focus on the relationships between the input and output of this “black box,” regardless of the internal complexities they would encounter in their future careers. He noted that unexpected outcomes often arise in theoretical studies. Additionally, Mr. Longxuan Chen emphasized the importance of mastering essential mathematical skills in calculus of variations, describing it as a valuable tool for anyone aspiring to develop a scientific theory, particularly for theoretical physicists. The education at USTC planted the seeds of science in Mr. Shi’s soul, but during China’s economic reform initiated by Xiaoping Deng, he gradually shifted his focus to a business career rather than fundamental scientific research.

In 1999, twenty years later, Mr. Shi had developed an interest in academic research on financial markets while working as an independent stock trader in Beijing since 1996. Drawing from his years of stock trading experience and with the assistance of two USTC classmates, Professor Huaiyu Wang and Associate Professor Youjiang Guo, from the Department of Physics at Tsinghua University, he revisited financial markets as complex systems. This exploration ignited his curiosity and led him to consult the physical and mathematical textbooks he had studied at USTC. His findings culminated in a paper published in Physica A in 2006, where he introduced a cumulative trading volume-price probability wave equation.
In June 2022, during a conversation with his then 9-year-old son, Haotian Shi, about the relationship between intelligent traders and complex systems, Mr. Shi began to ponder whether entangled particles possess intelligence-like properties, in addition to their wave-like characteristics. This intriguing question rekindled his passion for quantum physics. For over 90 years, quantum entanglement has posed challenges to the scientific community and remains a mystery.
Since then, Mr. Shi, as the lead author of a research group, has dedicated himself to understanding the underlying mechanisms of quantum entanglement and explaining its non-Gaussian distribution within the interdisciplinary field of complexity sciences (see Fig. 2) [8]. The theory was backed by a series of experiments on induced coherence and entanglement in optical interference dating back to 1991 [9-11]. His findings were eventually published in a paper on quantum interaction-coherent entanglement in the International Journal of Theoretical Physics.
This journey, spanning the bustling financial markets and the intricate world of quantum mechanics, showcases Mr. Shi’s passion for exploring complex systems. It also highlights the potential for interdisciplinary exploration to lead to groundbreaking discoveries in science.

Maintaining interaction-coherent entangled states, which are dissipative and energy-consuming, requires scientists and engineers to supply energy to complex quantum many-body systems. These pure states exhibit high fidelity, strong resistance to decoherence, and the ability to self-adapt, self-organize, and self-repair. Such characteristics suggest potential applications in quantum information technology, including wireless photon-entanglement communication via mobile phones, quantum computation, and quantum precision measurement.
From a thoughtful perspective, Mr. Shi intends to propose an adaptive behavioral theory for artificial general intelligence (AGI), based on a many-agent trading volume-price probability wave equation. Stock markets provide an excellent platform for studying human intelligence.
