Juliang Guangqi Raises $28M+ USD Angel Round to Industrialize Superconducting Quantum in China

May 18, 2026 — Shanghai-based startup Juliang Guangqi (矩量光启) has closed a RMB 200 million ($28M USD) angel round, one of the largest early-stage quantum hardware financings reported in China to date. The round was jointly led by semiconductor-focused investors Heli Capital and Junshan Capital, with participation from SMIC PE and other ecosystem players.

The company, founded in July 2025, positions itself as China’s first superconducting quantum computing startup to build from the ground up on industrial semiconductor production lines using silicon substrates. It recently completed an 8-inch industrial-grade wafer tape-out, a key manufacturing component.

The Technical Bet

While most early superconducting quantum work has used specialized substrates (e.g., sapphire) and lab processes, Juliang Guangqi is committing to silicon-based superconducting qubits compatible with mature CMOS processes, 3D stacking, TSVs, and chiplet technologies. The goal is better yield, uniformity, cost, and scalability by leveraging existing semiconductor infrastructure.

Founder Dr. Wenlong Yu brings a strong profile (USTC, Georgia Tech, Sandia National Labs, Alibaba DAMO). The team’s philosophy draws inspiration from Fairchild Semiconductor’s engineering-driven industrialization of silicon.

Why This Round Matters

The investor mix is of semiconductor VCs, SMIC PE, and other follow-on investment from seed investors. The mix reflects real industrial conviction, not just hype capital. It strengthens China’s position in superconducting quantum hardware while aligning with semiconductor self-reliance priorities.

Globally, it is one of the clearest signs yet of startups are trying to industrialize superconducting quantum by riding existing semiconductor capabilities vice reinventing a process in the lab. The piggyback industrialization is especially relevant as the field leans to fault-tolerant systems. Precisely the place where manufacturing scalability becomes a decisive factor.

Outlook

The round came just over a month after seed financing, showing strong momentum. Technical execution on qubit performance and scaling will ultimately decide success. With the combination of capital, credible backers, and a clear manufacturing thesis, this is one of the more noteworthy quantum hardware developments in China this year. It suggests serious industrial companies now see a potential path to scalable superconducting quantum hardware.
