TuringQ entered pre-IPO guidance for Shanghai's STAR Market in August 2026, putting it on track to become the first Chinese quantum computing company to list on a public exchange. Guotai Haitong Securities is sponsoring the filing, and it now sits with the China Securities Regulatory Commission for review. No listing date or share price range has been set yet. What's confirmed is the company's entry into the pipeline, not a completed IPO.
What TuringQ builds
TuringQ, founded in Shanghai in February 2021, makes photonic quantum chips, light-based processors that run at room temperature instead of the near-absolute-zero cooling superconducting qubits need. The company built a pilot production line in Wuxi in 2025 for wafer-scale lithium niobate photonic chip manufacturing, an existing optical-communications material and process rather than a purpose-built quantum fabrication line. That choice matters for a company chasing manufacturing scale: it borrows an established supply chain instead of building a new one from scratch.
TuringQ's controlling shareholder is Shanghai Siliang Quantum Technology, holding a 34.1% stake. The company raised roughly 1 billion yuan in 2026 funding, and a Series C round in April 2026 valued it above 7 billion yuan (close to $1 billion).
Why a STAR Market listing, not Nasdaq
Chinese quantum companies pursuing a US listing face a slower, more scrutinized path than they did a few years ago. The STAR Market, Shanghai's tech-focused board launched for companies not yet profitable, gives TuringQ a path to public capital without that friction. It's the same reasoning behind Chinese semiconductor and biotech firms choosing STAR Market listings over ADRs in recent years. TuringQ isn't alone in the pipeline either: Origin Quantum, Ciqtek, and QBoson are all pursuing listings of their own, which points to a coordinated push by China's quantum sector toward public markets rather than one company's individual decision.
What the filing confirms and what it doesn't
Confirmed: pre-IPO guidance status, the sponsoring securities firm, the exchange, and the regulatory body reviewing the application. Not yet confirmed: listing date, offering size, share price, or post-IPO valuation. Pre-IPO guidance in China's system is an early formal step, not a guarantee of a completed listing. Companies spend months or longer in this stage, and some withdraw before reaching a public offering.
TuringQ's photonic approach puts it in the same broad architecture category as Xanadu and PsiQuantum in the US, and OptQC in Japan, companies betting that room-temperature operation and existing optical manufacturing infrastructure outweigh the technical hurdles photonic qubits still face around gate fidelity and loss.
What to watch next
The next real milestone is a set listing date and offering size from the CSRC review, not further funding or valuation news. If TuringQ completes the listing, the number worth tracking afterward is real revenue disclosed in public filings, the same standard this site applies to IonQ, Rigetti, and D-Wave, rather than the pre-IPO valuation figures already circulating.
