Shanghai-based quantum startup Taiyi Quantum has raised $44 million to develop a next-generation computer.
Shanghai-based company Taiyi Quantum has closed a pre-seed funding round of 300 million yuan, equivalent to approximately $44 million. Key investors include funds Gaorong Venture Capital and IDG Capital — a strong signal of confidence in a technology that could radically transform the computing landscape.
Behind the project is Liu Hongbin, a former quantum systems architect at Microsoft's Azure Quantum project. His experience at the intersection of classical cloud technologies and quantum physics gives the startup unique expertise. Taiyi Quantum focuses on building a quantum computer operating on neutral ytterbium atoms. In this architecture, qubits are individual atoms held in optical traps using lasers.
The choice of ytterbium is no accident: this element demonstrates exceptional stability and low error rates in quantum operations. Unlike superconducting qubits requiring extreme cooling, neutral atoms can operate at higher temperatures, potentially reducing scaling costs. However, the main challenge is maintaining coherence and precisely controlling thousands of atoms simultaneously.
For the crypto industry, the development of quantum computing is a double-edged sword. On one hand, powerful quantum systems could break current cryptographic algorithms, including ECDSA, which protects Bitcoin. On the other hand, startups like Taiyi Quantum are driving the transition to post-quantum cryptography, which will strengthen blockchain security in the long term.
My expert assessment: Raising $44 million at such an early stage is a strong indicator that investors see neutral ytterbium atoms as a real alternative to the currently dominant superconducting approaches. If Liu Hongbin manages to scale the system to a commercially significant number of qubits within the next 3–5 years, we will witness a tectonic shift not only in computing but also in the foundations of cryptographic protection for digital assets.
