Xanadu

Xanadu is a quantum computing company that builds photonic quantum computers, making them accessible via the cloud. The threat model here isn't traditional network intrusion - it's the race to achieve practical quantum advantage, where the security implications of quantum hardware and the software ecosystems around it are foundational. The company operates at the intersection of hardware engineering, semiconductor manufacturing research, and open-source software development. Their technical stack spans photonic quantum hardware and quantum machine learning. A key artifact is PennyLane , their open-source software library for quantum machine learning and simulating quantum photonic devices, which has become a leading tool among quantum researchers and developers globally. Founded in 2016 and headquartered in Toronto, Ontario, Xanadu is recognized as one of the world's leading photonic quantum hardware providers. The team brings together researchers and engineers focused on advancing quantum computing through both proprietary hardware and community-driven software.
