Xanadu Tech Stack

Photonic quantum hardware and software stack for scalable quantum computing

Computer Hardware Manufacturing Toronto, Ontario 51–200 employees Privately Held

Xanadu builds photonic quantum computers using a full-stack approach spanning custom silicon (ASICs), optical components (superconducting single-photon detectors), and software libraries. The hiring mix skews heavily senior (18 of 27 mapped roles) across engineering, research, and finance—typical of hardware-stage quantum startups managing capital-intensive development and complex physics. Active projects center on fault tolerance, detector performance, and error correction, while pain points cluster around metrology, scaling detector arrays, and simulation complexity, revealing the core engineering constraint: moving from lab-grade to production-grade photonic systems.
