Trumpf Explores Quantum Computing to Enhance Laser Technology

Trumpf, the manufacturer of lasers critical to ASML's EUV chipmaking tools, is exploring the potential of quantum computing to enhance its laser technology. According to Tom's Hardware, Trumpf is collaborating with the Fraunhofer Institute for Laser Technology, also known as Fraunhofer ILT, and the Dahlem Center at Freie Universität Berlin. This partnership aims to investigate whether quantum computers can outperform classical supercomputers in optimizing CO2 laser systems, which play a significant role in semiconductor production, particularly in DUV and EUV lithography tools. The initiative is funded with approximately 1.8 million euros from Germany's Federal Ministry of Education and Research.

The project will focus on two main areas: the industrial applications of CO2 lasers and the scientific direction of microscopic explorations. Quantum computers may provide more efficient modeling of CO2 lasers due to the inherently quantum-mechanical nature of the physics involved, such as vibrational and rotational energy exchanges, molecular collisions, and population-inversion dynamics. Classical supercomputers struggle to accurately represent these complex interactions because they require approximations, while quantum computers can encode quantum states natively, making them better suited for simulating many-body interactions that affect the performance of CO2 lasers.

The initial task for the team is to determine the capability of quantum hardware to handle complicated quantum-mechanical interactions that govern how particles generate and amplify light. The Fraunhofer ILT will contribute its expertise in simulating semiconductor devices, while the Dahlem Center will focus on molecular collision dynamics. A key technical component will involve translating established energy-transfer behaviors into formats compatible with quantum algorithms. Trumpf is responsible for developing the first versions of these quantum algorithms, which will be tested for their effectiveness.

One of the early targets is to optimize CO2-laser amplification processes, which require precise predictions of energy transfer between molecular states to enhance optical output and overall system performance. Researchers have begun reviewing current simulation methods and benchmarking initial quantum approaches to identify potential advantages. Given that current quantum computers are largely experimental and lack the robustness for large-scale industrial workloads, the emphasis is on acquiring the necessary knowledge to utilize more advanced quantum machines in the future.

This includes validating whether specific parts of laser-physics models can run more efficiently on quantum hardware compared to traditional supercomputers. Additionally, the enhanced understanding of microscopic behaviors could inform future laser designs, leading to improved gain media and interactions between pump sources and active materials. Ultimately, more accurate predictions could result in higher performance, reduced power consumption, and more compact devices, which would be beneficial for applications using Trumpf's lasers, including lithography tools. Furthermore, advancements in CO2-laser modeling enabled by quantum algorithms could potentially lower the environmental impact of laser-based devices. However, as noted in the sources, this research is in its early stages, and the tangible impacts of quantum computing on CO2 laser technology remain largely speculative.
