What Is PsiQuantum?
PsiQuantum is a U.S.-based quantum computing company founded in 2016 by Jeremy O’Brien, Terry Rudolph, and Mark Thompson, with headquarters in Palo Alto, California. The company’s mission is to build a fault-tolerant, commercially useful quantum computer by leveraging manufacturing techniques proven at global semiconductor scale. PsiQuantum focuses on solving the scalability challenge in quantum computing, aiming to move the technology from laboratory prototypes to industrial-scale systems capable of addressing real-world problems.
Technology & Products
PsiQuantum’s technology is centered on photonic quantum computing, using single photons as qubits generated, manipulated, and measured on silicon photonic chips. Unlike approaches based on superconducting or trapped-ion qubits, PsiQuantum’s architecture is designed to be fabricated in advanced semiconductor foundries, enabling high-volume production and tighter process control. The company is pursuing a fault-tolerant architecture that incorporates quantum error correction from the outset, prioritizing system reliability over near-term, small-scale demonstrations. PsiQuantum does not market a commercial product today, instead focusing on building a full-scale quantum computer platform.
Market Opportunity
PsiQuantum operates in the emerging but potentially transformative quantum computing market, where demand is expected from industries such as chemistry, materials science, finance, logistics, and cryptography. Many of the most valuable quantum applications require millions of error-corrected qubits, far beyond the capabilities of current systems. By targeting large-scale, fault-tolerant quantum computing directly, PsiQuantum positions itself to address the highest-value use cases once the technology matures, rather than incremental or experimental workload.
Competitive Landscape
PsiQuantum competes with other leading quantum computing companies, including startups and large technology firms pursuing alternative qubit modalities such as superconducting circuits, trapped ions, and neutral atoms. Its key differentiation is a manufacturing-first strategy, relying on silicon photonics and existing semiconductor infrastructure to achieve scale. While competitors may demonstrate earlier milestones with smaller systems, PsiQuantum’s approach emphasizes long-term scalability and commercial viability, positioning it as a high-conviction bet on the future of fault-tolerant quantum computing.
How To Buy PsiQuantum Stock?
PsiQuantum is currently a private company and is not publicly traded on major stock exchanges like the NASDAQ or NYSE. This means you can buy shares through a pre-IPO platform or brokerage like IPO CLUB.
