Thesis
Quantum infrastructure and components are critical picks-and-shovels plays for the nascent quantum computing market and the accelerating AI supercycle. Demand for advanced photonics, cryogenic testing, and precision control systems is robust, driven by the fundamental shift to optical interconnects and the scaling of quantum processors.
Bull case
The explosive demand for AI infrastructure is driving a fundamental shift from electrical to photonic interconnects, creating a massive tailwind for high-bandwidth, low-latency optical components and systems. This includes 800G/1.6T transceivers, co-packaged optics (CPO), and advanced packaging, which are crucial for next-generation AI data centers and directly benefit theme constituents. The quantum photonics market is projected to grow at a 26.9% CAGR from 2026 to 2035.
Significant advancements in quantum hardware, including breakthroughs in error correction and the emergence of hybrid quantum-classical computing, are fueling demand for specialized infrastructure and components. This includes cryogenic test solutions, advanced control systems, and specialized lasers/optics that enable the development and characterization of increasingly complex quantum processors, moving quantum from research to an engineering discipline.
Both private and public investment in quantum technologies is surging, with enterprise spending surpassing government/academia for the first time in 2025. This capital inflow, coupled with a focus on building quantum ecosystems and distributed quantum computing architectures, drives demand for "picks and shovels" providers in semiconductors, AI, cloud, and data infrastructure, offering more immediate commercial opportunities than pure-play quantum.
Bear case
Despite rapid progress, quantum computing remains technologically immature. Fundamental challenges like qubit decoherence, the need for extreme cryogenic temperatures for many modalities, and the immense engineering task of scaling to millions of fault-tolerant qubits persist. Widespread commercial viability for most enterprises is still projected for the early 2030s, introducing significant long-term execution risk.
Indium Phosphide (InP), a critical material for high-speed optical interconnects, faces a severe supply-demand imbalance, exacerbated by China's export controls since 2025. The concentration of InP production among a few suppliers and in geopolitically sensitive regions creates significant supply chain vulnerabilities, driving up costs and potentially limiting the growth of AI optical infrastructure.
Companies in this nascent sector require substantial ongoing investment in R&D, manufacturing capacity, and personnel to overcome technical hurdles and scale operations. While strategic, these high operating expenses and capital expenditures can pressure profitability and cash flow in the near to medium term, especially for pure-play quantum companies, making the path to sustained profitability uncertain and leading to speculative valuations.
