PsiQuantum, a U.S.-based startup with significant Australian investment, has announced a major milestone in quantum computing: the ability to produce millions of quantum chips at the volume necessary to make commercially viable machines. This breakthrough addresses one of the most significant challenges in quantum computing—the mass manufacturing of quantum chips.
Quantum computing has the potential to outperform even the most advanced AI systems and could revolutionize industries like cyber security, drug discovery, and materials research. However, scaling production for quantum chips has been a longstanding issue.
The Photon-Based Approach
The company’s solution lies in using photonics—a technology widely used in communications semiconductor manufacturing. PsiQuantum’s chip, Omega, leverages photonic methods to manipulate light particles (photons) for quantum calculations. This approach is advantageous because it requires less complex cooling systems for the quantum devices.

PsiQuantum CEO Jeremy O’Brien highlighted that this isn’t just a breakthrough in research but a fully matured technology ready for mass production. The company has partnered with GlobalFoundries to produce these chips at its Albany, New York facility. The process uses industry-standard 45-nanometer wafers, achieving manufacturing yields comparable to those of traditional semiconductors.
Path to Commercialization
The startup’s technology is expected to support quantum computing machines in a more efficient and scalable manner, opening doors for new commercial applications. O’Brien indicated that PsiQuantum plans to have a commercial quantum computer in place within six years, with a fully operational facility for commercial applications set to be completed by 2027.
PsiQuantum’s success follows major quantum computing advancements from other tech giants. Microsoft recently showcased a different type of quantum chip, while Google revealed a breakthrough that could lead to commercial applications in the next five years.
