The quiet calculus behind ASML’s revised forecast, and what it signals for China’s quantum and chip ambitions

On Wednesday, Dutch semiconductor lithography giant ASML raised its full-year 2026 net sales forecast to a range between €36 billion and €40 billion, up from its January estimate of €34 billion to €39 billion. The upgrade was driven by robust global demand for advanced chipmaking equipment, even as the company disclosed that China’s share of its shipments continued to shrink and that it was bracing for a potential new round of United States export restrictions targeting China. The announcement, released alongside first-quarter results, offers a rare, granular window into the tectonic shifts reshaping the global semiconductor landscape — shifts with direct consequences for China’s long-term ambitions in high-performance and quantum computing.

ASML occupies a uniquely strategic position in the global chip ecosystem. It is the sole manufacturer of extreme ultraviolet (EUV) lithography machines, which are essential for producing the most advanced microchips. Chinese chipmakers, already restricted from purchasing these EUV tools under existing US-led export controls, have been limited to older deep ultraviolet (DUV) systems — and even those are now subject to tightening curbs. The company’s latest outlook confirms that this policy pressure is having a measurable effect: as demand surges elsewhere, China’s proportional access to ASML’s tools is narrowing.

For China’s quantum computing ecosystem, the implications are both indirect and profound. Leading approaches to building scalable quantum processors — including superconducting qubit architectures and silicon spin qubits — often draw upon advanced semiconductor fabrication techniques developed and perfected for classical chips. China has invested heavily in domestic lithography research through entities such as Shanghai Micro Electronics Equipment (SMEE) and academic institutes, but the gap between domestic capabilities and ASML’s technology remains considerable. The tightening of access to leading-edge tools not only slows China’s progress in conventional advanced-node chip production; it may also constrain the development of certain quantum hardware platforms, which rely on the same lithographic precision to define qubit structures and control electronics.

Equally significant is the broader strategic response the export restrictions are provoking. Faced with limited access to foreign technology, China has accelerated indigenous innovation across the semiconductor value chain, from chip design software to materials science and manufacturing equipment. There are early signs that this pressure is stimulating alternative approaches: photonic quantum computing, for example, which does not rely on the same fabrication ecosystem as lithography-dependent qubit platforms, has received robust research funding and institutional support in China. The nation’s push toward self-reliance may, over time, yield quantum architectures that follow a different technological trajectory than the ones currently led by US and European incumbents.

Why it matters:
ASML’s revised forecast underscores a strategic reality: the technological bottlenecks China faces in quantum computing are not limited to qubit coherence times or error correction, but extend deep into the industrial base of chipmaking itself. For investors, researchers, and policy professionals, the narrowing channel between China and advanced semiconductor tools signals that the race for quantum advantage will be shaped as much by geopolitics and supply-chain architecture as by laboratory breakthroughs.
