Extreme Ultraviolet News
Xanadu Quantum Technologies Inc. and Mitsubishi Chemical Corporation have achieved a breakthrough in simulating the complex quantum processes needed to make the world’s most advanced microchips, advancing the semiconductor and quantum computing industries. Quantum simulation method designed to solve extreme ultraviolet (EUV) lithography problems.
This announcement comes as Xanadu is ready for a big organizational change, involving a multi-million dollar merger that will likely make it the first pure-play photonic quantum computing company to be listed on the Toronto Stock Exchange and the Nasdaq.

Overcoming the “Blurring” Barrier in Chip Fabrication
The semiconductor industry has become more and more dependent on EUV lithography as the need for high-performance electronics, from supercomputers to artificial intelligence, continues to rise globally. This method makes it possible to create smaller and more intricate integrated circuits by patterning silicon wafers using light with incredibly short wavelengths. However, manufacturers have a “formidable challenge” as these characteristics approach near-atomic scales: radiation-induced blurring.
The accuracy and potency of the final chips are diminished by this blurring effect. It is fueled by a combination of chemical and electronic dynamics, including secondary electron behavior and Auger decay. Since these interactions are fundamentally quantum-mechanical, it has been practically hard to adequately simulate them with traditional computing techniques.”The semiconductor industry faces a significant challenge in accurately modeling materials’ interactions with EUV light,” said Christian Weedbrook, Xanadu‘s founder and CEO. The partnership has developed a blueprint for resolving one of the most pressing issues in the contemporary semiconductor business by using quantum algorithms to address these particular chemical sensitivities.

The Breakthrough: A Scalable Quantum Suite
One of the earliest tangible industrial applications of quantum computing in the semiconductor industry is presented by the study. The algorithms are made to operate on utility-scale fault-tolerant quantum computers (FTQCs), which are devices that can fix mistakes on their own when performing intricate computations.
The effectiveness of the suggested techniques is one of the research’s main highlights. The researchers showed that the simulation could accurately anticipate important aspects of the EUV photoabsorption spectrum using fewer than 500 qubits for a target model system, 4-Iodo-2-methylphenol. Because it enables the algorithms to run on early-generation FTQC machines, such as those Xanadu is currently developing, this low resource need is crucial.
It has been a “long-standing challenge” to precisely describe these dynamics, according to Qi Gao, Senior Chief Scientist at Mitsubishi Chemical. The new findings open the door to better photoresist design, the light-sensitive substance used to cover wafers during the patterning process, by showing promising approaches to modeling the radiation-driven processes that previously had restricted lithographic resolution.

A Year of Strategic Collaboration
A collaborative project that was formally initiated on July 2, 2025, produced the breakthrough. The collaboration brought together the extensive subject-matter knowledge of two world leaders:
- Mitsubishi Chemical’s Materials Design Laboratory: Fundamental knowledge and quantitative study of EUV photoresist materials, including their molecular structures, reactivity, and processes like photoabsorption and Auger decay, were provided by Mitsubishi Chemical’s Materials Design Laboratory.
- Xanadu’s Quantum Algorithms Team: Used their expertise to create simulation algorithms that simulate the interactions of secondary electrons, matter, and light.
These kinds of advances in material science are essential to the ongoing shrinking of chips, according to Torin Stetina, Senior Quantum Scientist at Xanadu. An “exciting frontier” for the industry is the potential of quantum simulation to reveal material attributes for upcoming semiconductor generations.
Corporate Growth and the Path to the Public Market
The technological innovation comes at a time when Xanadu is expanding quickly. The company and Crane Harbor Acquisition Corp., a special purpose acquisition company (SPAC), recently signed a business combination agreement. The merged company, Xanadu Quantum Technologies Limited (“NewCo”), is anticipated to list on the Toronto Stock Exchange and the Nasdaq Stock Market after this merger is finalized.
The change has a significant financial impact. It is anticipated that NewCo will be funded using roughly $500 million in gross profits. This comprises:
- US$225 million (assuming no redemptions) from Crane Harbor’s trust fund.
- US$275 million through a common equity committed private placement (PIPE) from a consortium of institutional and strategic investors.
The momentum of Xanadu goes beyond this merger. The business recently secured up to $15 million in funding, reached Stage B of DARPA‘s Quantum Benchmarking Initiative, and opened a $10 million advanced photonic packaging factory in Ontario. In addition, Xanadu has worked with AMD to speed up quantum workflows and integrated its open-source PennyLane software with the Munich Quantum Toolkit.

The Broader Vision: KAITEKI and Global Leadership
The 1933-founded business Mitsubishi Chemical, the collaboration supports its objective of becoming a “Green Specialty Company.” To realize KAITEKI, a Japanese concept that symbolizes the welfare of both people and the world, the firm aims to apply materials science. Mitsubishi wants to provide “impressive results” in industries like communications, healthcare, and mobility by using creative solutions to address social and industrial issues.
The importance of this global collaboration has also been acknowledged by the Canadian government. “Decades of strategic investment have made Canada a global leader in quantum technology,” said Mr. Louis-Pierre Émond, Minister (Commercial) of the Canadian Embassy to Japan. The partnership between a Japanese chemical behemoth and a Canadian quantum pioneer demonstrates how international the race to develop practical quantum technology is.
Future Outlook and Risks
The path to complete commercialization is still difficult, even though the study report offers a scalable method for the future. Regarding their proposed business combination, Xanadu and Crane Harbor have submitted a registration statement on Form F-4 to the SEC. The “substantial doubt” about Xanadu’s capacity to remain a going concern in the absence of successful funding or expansion, as well as the “significant technical challenges” related to developing technologies, are among the risks connected with forward-looking statements; investors are warned.
But a significant turning point has been reached with the development of one of the first tangible industrial applications for quantum computing in semiconductors. The “blueprint” offered by Xanadu and Mitsubishi Chemical might end up becoming the norm for how future hardware is designed globally as chip features continue to get smaller.
