The year 2025 marks both the "International Year of Quantum Science and Technology" and a pivotal phase where quantum advancements accelerate from theoretical research to industrial applications. Major global economies are intensifying their quantum strategies, with China positioning quantum technology at the forefront of its 15th Five-Year Plan for future industries. Quantum computing—the crown jewel of quantum technologies—boasts the highest technical barriers, most disruptive potential, and greatest growth prospects. By enabling exponential computational breakthroughs, it promises to redefine classical computing boundaries and serve as the critical engine for the next technological revolution. Currently, quantum computing operates in the Noisy Intermediate-Scale Quantum (NISQ) era, with superconducting, ion trap, photonic, and neutral-atom approaches advancing in parallel without clear convergence. Industry focus remains on upstream and midstream segments of the supply chain. The sector is entering a rapid growth phase, with global market size projected to exceed $800 billion by 2035. While downstream applications remain nascent, their potential is immense.
**Redefining Computational Frontiers and Leading Future Industries** Quantum computing leverages quantum phenomena to overcome classical computational limits. As it progresses through the NISQ era, multiple technical pathways—including superconducting, ion traps, photonics, and neutral atoms—are driving practical and scalable solutions. China’s 15th Five-Year Plan prioritizes quantum technology, with the Ministry of Industry and Information Technology spearheading standardization efforts to outline industrial development. Globally, nations are racing to secure strategic advantages in this emerging battleground.
**Divergent Technical Pathways with Upstream/Midstream Focus** The upstream supply chain covers quantum chips, environmental control systems, and critical components, where the absence of a dominant technical approach has prevented clear competitive dynamics. Midstream involves quantum computer hardware and software algorithms, with cloud platforms likely becoming key to downstream adoption due to high hardware costs and algorithmic complexity. Downstream applications span research, finance, chemicals, and pharmaceuticals but have yet to demonstrate exponential acceleration or quantum advantage at scale, leaving room for exploration from theory to commercialization.
**High-Growth Market Potential** Photonics Box Research forecasts quantum computing entering a high-compound-growth phase, with global industry scale expanding from ~$5 billion in 2024 to ~$800 billion by 2035—capturing nearly 90% of the quantum technology market. Upstream sectors show relative maturity and strong growth, while downstream applications—though currently valued at $270 million—could surge to $202.67 billion by 2035. Procurement markets concentrate on upstream equipment, with research dominating early adoption.
**Key Risks** 1. **Core Technology Delays**: Challenges like qubit decoherence and immature error correction hinder large-scale integration. No existing pathway currently supports million-qubit practicality. 2. **Fragmented Ecosystem**: Competing standards and scarce software tools/algorithms persist, with critical components reliant on imports. 3. **Limited Commercialization**: Most applications remain lab-bound, lacking scalable use cases or viable business models. 4. **Policy Gaps**: Export controls tighten globally, while inconsistent regulations and inadequate commercialization support create uncertainty. 5. **Investment-Return Mismatch**: Heavy R&D costs strain profitability, with unclear payback timelines raising funding risks.
