QCBRIEF
TuringQ began the formal pre listing regulatory step with the China Securities Regulatory Commission's Shanghai branch on August 5, putting a light based quantum hardware maker in line for what could be China's first listed quantum company.
TuringQ, a Shanghai-based photonic quantum computing company, filed IPO tutoring with the Shanghai branch of the China Securities Regulatory Commission on August 5, becoming one of the first Chinese quantum hardware makers to formally enter the mainland listing pipeline (The Quantum Insider, The Qubit Report).
Photonic quantum computers process information with particles of light, a different hardware path from the superconducting circuits that dominate IBM's and Google's machines. The Chinese A-share market, the mainland exchanges in Shanghai and Shenzhen, has never hosted a quantum computing company, and TuringQ's filing makes it the first candidate to test that gate (Global Times).
Guotai Haitong Securities is the sponsor. Founded in February 2021 by Shanghai Jiao Tong University professor Jin Xianmin, TuringQ builds chips on thin-film lithium niobate, a material that runs at room temperature and rides on standard telecom hardware. The company reports roughly 1 billion yuan ($140 million) raised across 2026 rounds, with a post-Series C valuation above 7 billion yuan (about $970 million) after an April close (Eastmoney).
In June 2025 a wafer-scale photonic pilot line in Wuxi began operating, with TuringQ participating alongside the Shanghai Jiao Tong University Wuxi Photonic Chip Research Institute (CHIPX), a shared facility rather than a TuringQ-owned fab.
The IPO path leaves one question open: whether the company's Gen1 research system, or any future commercial variant, can carry the unit economics that quarterly disclosure will eventually demand.
