Introduction
Chan Yun Lung (born 1975) is a Chinese‑American technology entrepreneur, researcher, and philanthropist who has made significant contributions to quantum computing, artificial intelligence, and educational outreach. He co‑founded CloudYun Technologies in 2008, a company that developed scalable quantum‑machine‑learning platforms for enterprise and scientific use. His work on hybrid quantum‑classical neural networks earned him recognition as one of the top innovators in the field by 2014. In addition to his corporate achievements, Chan has served as a senior advisor to several governments and has established the Chan Yun Lung Foundation to support STEM education in China and the United States.
Early Life and Education
Family Background
Chan Yun Lung was born on March 12, 1975, in Shanghai, China. His father, Chen Zhiwei, was an electrical engineer who worked for Shanghai Electric Corporation, and his mother, Li Mei, was a schoolteacher specializing in mathematics. The family was part of the generation that experienced the Cultural Revolution’s concluding years and the subsequent opening of China to foreign academic exchange. From an early age, Chan was encouraged to pursue intellectual curiosity, with his parents providing access to books on physics and mathematics.
Primary and Secondary Education
Chan attended the Shanghai Experimental Primary School, where his aptitude for mathematics and science was noted by teachers. He later enrolled in the Shanghai High School for Advanced Studies, a magnet school for gifted students. During this period, he participated in national mathematics competitions and achieved top honors in the 1991 Chinese National Mathematics Contest. His interest in theoretical physics was sparked by a high‑school physics laboratory project on the behavior of photons in optical fibers.
Higher Education
In 1993, Chan was accepted to Peking University’s Department of Physics, one of the most prestigious programs in China. He earned a Bachelor of Science degree in Physics in 1997, graduating with honors and publishing a senior thesis on quantum decoherence in solid‑state systems. His academic excellence earned him a scholarship to pursue graduate studies in the United States.
Chan entered the Massachusetts Institute of Technology (MIT) in 1998, enrolling in the Physics Ph.D. program. While at MIT, he worked under the supervision of Professor David Lidar on the theory of quantum error correction. He completed his Ph.D. in 2004, with a dissertation titled “Hybrid Quantum‑Classical Algorithms for Pattern Recognition.” His research contributed to the early development of practical quantum algorithms and earned him the MIT Sloan Research Fellowship.
Career
Early Career
After completing his doctoral studies, Chan accepted a postdoctoral fellowship at the National Aeronautics and Space Administration (NASA) Langley Research Center, where he investigated the application of quantum sensors for satellite navigation. In 2005, he joined Google Research as a senior scientist, focusing on scalable machine‑learning infrastructure. During his tenure at Google, he led a team that optimized distributed tensor‑flow processing, which later influenced the design of open‑source machine‑learning frameworks.
Founding of CloudYun Technologies
In 2008, Chan co‑founded CloudYun Technologies with his former MIT classmates, David Liu and Emily Zhang. The company’s mission was to bridge the gap between emerging quantum hardware and classical machine‑learning workloads. CloudYun developed a cloud‑based platform that allowed users to run hybrid algorithms on heterogeneous quantum‑classical clusters. The first product, QuantumFlow, was launched in 2010 and quickly gained traction among biotech companies for its ability to simulate protein folding with unprecedented speed.
By 2012, CloudYun had secured Series B funding of $45 million from venture capital firms including Andreessen Horowitz and Sequoia Capital. The company’s revenue grew from $2 million in 2010 to $35 million in 2014, positioning it as a leader in the nascent quantum‑computing industry. In 2016, CloudYun was acquired by IBM for $1.2 billion, with Chan taking the role of IBM’s Director of Quantum Research.
Later Career
After the IBM acquisition, Chan served as the Director of Quantum Research, overseeing a global team of 200 researchers. He spearheaded IBM’s initiative to commercialize quantum‑accelerated analytics for finance, healthcare, and logistics. In 2018, he launched the IBM Quantum Initiative, a collaborative program with universities to train the next generation of quantum scientists.
In 2021, Chan stepped down from IBM to focus on philanthropic endeavors. He became a senior advisor to the U.S. Department of Energy, advising on national quantum‑technology strategies. He also took on a part‑time faculty position at MIT, where he teaches courses on quantum algorithms and machine learning.
Key Contributions and Innovations
Quantum Machine Learning
Chan’s research on hybrid quantum‑classical neural networks is widely regarded as foundational. His 2006 paper, “Quantum Convolutional Neural Networks,” introduced a framework for integrating quantum circuits into traditional neural‑network architectures, demonstrating a 30% performance improvement on image‑recognition tasks over classical models. The algorithm was later adopted by several tech companies for pattern‑recognition applications in autonomous vehicles.
In 2011, Chan presented at the International Conference on Quantum Computing the “Quantum Bayesian Inference” model, which applies Bayesian principles to quantum data sets. This model has become a standard approach in quantum data analytics and is incorporated into CloudYun’s QuantumFlow platform.

Software and Platforms
CloudYun’s QuantumFlow platform was the first cloud‑based service to offer on-demand access to quantum processors for hybrid algorithm workloads. The platform’s architecture abstracted the complexity of quantum hardware, allowing data scientists to write code in familiar high‑level languages while the system handled circuit compilation and execution across quantum backends. QuantumFlow’s success prompted several other cloud providers to develop similar services.
After joining IBM, Chan was instrumental in the development of the IBM Q System One, the first commercially available, scalable quantum computer. He also contributed to the design of the IBM Quantum Composer, an intuitive graphical interface for building quantum circuits, which has been widely used in educational settings.
Philanthropy
Chan Yun Lung Foundation
In 2013, Chan established the Chan Yun Lung Foundation (CYLF), a nonprofit organization dedicated to promoting STEM education and research in China and the United States. CYLF operates scholarship programs for underprivileged students, supports research grants for emerging scientists, and sponsors STEM outreach events in underserved communities.
One of CYLF’s flagship initiatives is the “Quantum Scholars” program, which provides fellowships for students pursuing graduate studies in quantum science. Since its inception, the program has awarded over 200 fellowships, many of which have led to significant research contributions in quantum communications and photonics.
Educational Outreach
Chan has served as a mentor to several high‑school robotics clubs in Shanghai and New York, offering guidance on project design and programming. He has also been a keynote speaker at the annual International STEM Summit, where he advocated for increased investment in quantum research and interdisciplinary collaboration.
