The company’s approach to fault-tolerant quantum computing is based on leveraging photonic qubits and semiconductor manufacturing. In 2019, PsiQuantum announced a manufacturing partnership with GlobalFoundries to produce silicon photonic quantum devices in a commercial semiconductor foundry in upstate New York. [...] In early 2021, researchers from PsiQuantum introduced Fusion-Based Quantum Computing (FBQC), a fault-tolerant quantum computing architecture based on entangling measurements and photonic qubits. The company has described FBQC as a key element of its approach to large-scale quantum computing. In 2022, PsiQuantum began transitioning production into GlobalFoundries' Fab 8 facility in New York. The same year, the company announced a partnership and $22.5 million contract with the U.S. Air Force Research Laboratory (AFRL) focused on photonic quantum technologies.

    Learn more View all private companies ### Description PsiQuantum is focused on developing and deploying utility-scale, fault-tolerant quantum computers by leveraging silicon-photonics and advanced semiconductor manufacturing. The company claims to be building wafers of quantum chips, testing production cryogenic cabinets, and optimizing quantum algorithms. PsiQuantum acknowledges its commitment to serving as a government partner, while applying the technology to sectors like sustainability, healthcare, finance, transportation, and security. ### PsiQuantum Palo Alto, CA US Sector: : Hardware Industry: Computer, Hardware, Quantum Computing, Semiconductor, Software Full Time Employees: : 501 ### Key Executives [...] Intense Competition and Market Uncertainty: PsiQuantum operates in a highly competitive market where different qubit technologies (superconducting, trapped-ion, photonic, etc.) are vying for dominance. Competitors like IBM, Google, and Quantinuum have demonstrated working quantum computers. The market is still uncertain about which technology will ultimately be the most scalable and commercially viable. This uncertainty poses a risk to PsiQuantum, as a major breakthrough from a rival using a different technology could swiftly erode its market position and investor confidence. [...] Technological Advancement and Patented IP: PsiQuantum continues to advance its core technology, which is based on a photonic approach that leverages standard semiconductor manufacturing. The company announced its new Omega chipset in February 2025, which is purpose-built for utility-scale quantum computing. It has also recently launched "Construct," a dedicated software suite for designing fault-tolerant quantum algorithms. This dual focus on both hardware and software, combined with its large portfolio of patents, provides a significant competitive advantage by creating a potential comprehensive, end-to-end solution for a fully fault-tolerant quantum computer.

  • PsiQuantum - Building the world’s first useful quantum computers.

    ## Overview Quantum computing will be a world-changing technology with the potential to unlock powerful advances in medicine, energy, finance and beyond. At PsiQuantum, we’re focused on building the world’s first useful quantum computer. A useful quantum computer requires at least 1,000,000 qubits and error correction. We believe photonics is the only path to building a useful quantum computer. Our team at PsiQuantum is a mix of quantum physicists, semiconductor, systems, and software engineers, system architects and more. Error correction is at the centre of everything we do; and we focus on solving real-world problems. If you’re interested in joining our team, we are always open to hearing from exceptional people interested in working on one of the defining technologies of our lifetime. [...] [Likes: 177, Comments: 3]; Mark Thompson (1w): I'm excited to share that we're continuing to grow the PsiQuantum UK R&D team at PsiLabs, Daresbury Laboratories. If you're looking for an opportunity to work on genuinely groundbreaking technology, alongside exceptional engineers and scientists, this could be a great time to join us. PsiQuantum is building the world's first useful, fault-tolerant quantum computer, and our UK team is playing a critical role in making that vision a reality. Opened in 2023, PsiLabs at Daresbury Laboratories, positioned between Liverpool and Manchester, is home to a growing R&D team developing technologies that will help enable large-scale quantum computing. It's an environment where fundamental science meets world-class engineering, and where difficult

  • PsiQuantum Supercomputer: Aiming for a Million Qubits - IEEE Spectrum

    Colby Macri/PsiQuantum In an industry where timelines are often fuzzy and subject to revision, the quantum-computing company PsiQuantum has set itself an aggressive target. The California-based startup has committed to building a fault-tolerant quantum computer with roughly a million qubits by 2027. And the company is now in the process of assembling its first fully fledged prototype in a former semiconductor fabrication facility in California. Crossing the million-qubit threshold could start to realize quantum computing’s promise to revolutionize areas like materials science and chemistry.
