Xanadu and Mitsubishi Chemical Detail Quantum Algorithms for EUV Semiconductor Research
Xanadu Quantum Technologies and Mitsubishi Chemical have published a pre‑print detailing quantum simulation algorithms aimed at improving extreme ultraviolet (EUV) lithography, a key step in advanced semiconductor manufacturing. The approach models the quantum‑driven radiation‑induced blur that limits pattern fidelity, using a technique that can run on fault‑tolerant quantum computers with fewer than 500 qubits. A test case on the molecule 4‑Iodo‑2‑methylphenol demonstrates the method’s ability to predict EUV photoabsorption spectra. The paper marks one of the first concrete industrial use cases for quantum computing in chip R&D, promising smaller, more complex devices.
