Xanadu Quantum Technologies

Xanadu Quantum Technologies is a Canadian quantum computing hardware and software company headquartered in Toronto, Ontario. The company develops cloud accessible photonic quantum computers and develops open-source software for quantum machine learning and simulating quantum photonic devices.
History.
Xanadu was founded in 2016 by Christian Weedbrook and was a participant in the Creative Destruction Lab's accelerator program. Since then, Xanadu has raised a total of $45.5M in funding with venture capital financing from OMERS Ventures, Georgian, Real Ventures, Golden Ventures and Radical Ventures and innovation grants from Sustainable Development Technology Canada and DARPA.
Technology.
Xanadu's hardware efforts have been focused on developing programmable Gaussian Boson Sampling (GBS) devices. GBS is a generalization of Boson Sampling, which traditionally uses single photons as an input; GBS uses squeezed states of light. In 2020, Xanadu published a blueprint for building a fault-tolerant quantum computer using photonic technology.
