About Buchou Quantum
Buchou Quantum is a manufacturer of atomic quantum computing systems focused on enabling fault-tolerant computation and practical algorithm applications. The company was founded in 2025 and is headquartered in Shanghai, China. It originated as a spin-off from Fudan University and is a notable result of Shanghai's “Grant-Investment Linkage” policy, where venture capitalists are invited to evaluate government-funded research milestones. In December 2025, Buchou Quantum completed its Angel round of funding with investors including CAS Star, Furong Capital, and Oriental Fortune Capital. The company develops modular architectures, integrated software-hardware platforms, and advanced quantum measurement techniques using neutral atoms (Rubidium/Cesium) trapped by optical tweezers. Buchou Quantum has reportedly developed a prototype with 1,000 atomic qubits. Its systems are designed to provide scalable quantum processing with enhanced stability and precision. The primary clients for these solutions are research institutions and high-end computing industries. Keywords: neutral atom quantum computing, fault-tolerant quantum computation, modular architectures, integrated software-hardware, quantum measurement, optical tweezers, atomic qubits, rubidium, cesium, quantum processing, scalable quantum
