The link is for the paper related to Chris Lee's write up in arstechnica today: https://arstechnica.com/science/2021/03/programmable-optical... To make it easier for people, in the article Chris Lee cites this paper by Xanadu researchers: https://www.nature.com/articles/s41586-021-03202-1 arxiv version: https://arxiv.org/pdf/2103.02109.pdf, which is what I've put in the url of this post. Chris summarizes his thoughts as: "...this is a big step. There are no large barriers to scaling this same computer to a bigger number of qubits. The researchers will have to reduce photon losses in their…

I was going to submit exactly this but you beat me to it. ;) To make it easier for people, in the article Chris Lee cites this paper by Xanadu researchers: https://www.nature.com/articles/s41586-021-03202-1 arxiv version: https://arxiv.org/pdf/2103.02109.pdf Chris summarizes his thoughts as: "...this is a big step. There are no large barriers to scaling this same computer to a bigger number of qubits. The researchers will have to reduce photon losses in their waveguides, and they will have to reduce the amount of leakage from the laser that drives everything (currently it leaks some light…
