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[1][2][3][4] and innovation grants from Sustainable Development Technology Canada[5][6][7][8] and DARPA.[9]


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.[10][11][12][13][14][15] In 2020, Xanadu published a blueprint for building a fault-tolerant quantum computer using photonic technology.[16]
