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 US$245M in funding with venture capital financing from
Bessemer Venture Partners , Capricorn Investment Group,
Tiger Global Management ,
In-Q-Tel ,
Business Development Bank of Canada ,
OMERS Ventures , Georgian, Real Ventures, Golden Ventures and Radical Ventures

[20] and
DARPA .
[21]
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 .
[22]
[23]
[24]
[25]
[26]
[27] In 2020, Xanadu published a blueprint for building a fault-tolerant quantum computer using photonic technology.
[28]
In June 2022 Xanadu reported on a boson sampling experiment
summing up to those of Google and
University of Science and Technology of China (USTC) . Their setup used loops of optical fiber and
multiplexing to replace the network of
beam splitters by a single one which made it also more easily reconfigurable. They detected a mean of 125 to 219 photons from 216
squeezed modes (squeezed light follows a photon number distribution so they can contain more than one photon per mode) and claimed to have obtained a speedup 50 million times bigger than previous experiments.
