Xanadu AI, Canadian Quantum Computing Ponzi scheme, gets an extra CAN$32 Million

In a previous blog post, I commented about Xanadu AI:

Xanadu.ai, a quantum computing Theranos, will never make a profit

The latest news about the Xanadu Ponzi scheme is that they just got an extra CAN$32 Million (This raises their total funding so far to CAN$41M, according to TechCruch). This company has practically zero chance of succeeding. Their quantum computing technology, using squeezed light, is **far inferior** to the ones (ion trap, squids, optical, anyons, quantum dots) being pursued by a crowded field of well funded startups (Rigetti, IonQ, PsiQ, and many others) and giant monopolies (IBM, Google, Microsoft, Intel, Alibaba, Huawei, …).

The latest 32 million was reported in the Globe and Mail:

Toronto startup Xanadu raises $32-million to help build ‘world’s most powerful computer’

Excerpts in boldface:

But Xanadu needs to take “three giant steps,” before it can fully commercialize its technology, said Massachusetts Institute of Technology mechanical engineering and physics professor Seth Lloyd, a leading expert in quantum computing who advises the startup:

“They need to improve the squeezing by a significant amount and show they can get many pulses of this squeezed light into their device, and then control these pulses … [then] show you can actually do something that’s useful to people with the device. Given what they’re trying to do, they’re on schedule. Any one of those things could fail, which is the nature of science and life and being a startup.”

Only that, just a cake walk away. Right on schedule?? Squeezed light was invented by H. P. Yuen in 1976, 43 years ago. Brilliant experimentalists like Bernard Yurke and Jeffrey Kimble soon hit a brick wall in the amount of possible squeezing attainable. I hardly think that the CEO of Xanadu, Elizabeth Holmes or whatever his name is, can improve much on what they did. Nowadays, squeezing is used mainly by the LIGO people. I believe it might reduce their noise by a factor of 10 or so, but is that enough for Xanadu’s speculative analog quantum computer to perform calculations better than a cell phone. Highly doubtful.

The only thing that is on schedule here is Seth Lloyd’s Ponzi scheme.

Xanadu is looking to generate revenue in the short term with proof-of-concept projects for a few customers including Bank of Montreal, and by offering cloud-based software that customers can use to test out not only its quantum technology, but that of its competitors. Lawrence Wan, chief architect and head of enterprise platforms with BMO, said Xanadu’s approach “looks to be more commercially viable and scalable” than others.

Obvious BS. Why would the competitors with qc machines allow Xanadu to poach their clients? Besides, Xanadu’s underperforming or nonexistent squeezed light “quantum computer” is very different from a gate model machine so Xanadu is not especially qualified to advise others about gate model machines. Dozens of companies are already offering qc consulting services. Consulting won’t generate enough near-term revenue for Xanadu in the next 5-10 years of toy qc machines to cover the cost of the very expensive hardware R&D effort that they are “promising” to undertake.

Let’s face it, the real revenue maker for Xanadu is their Ponzi scheme.
