PROMs and EPROMS for deep learning in photonic neural networks. And it looks like they actually created a working chip. It is difficult to imagine the future implications of this achievement.
So this is where they would store the model and just push input through it?

fyi, already posted in economics thread, but this is the better place for it

What does it mean for China to impose export controls on something that it is probably behind the West on. Or at least that's my perception

Symbolic move in response to US sanctions on Chinese entities due to alleged military aid to Russia?

So there are a few possibilities that come to mind:

1) China recently achieved approximate parity with the West when it comes to these categories. Preventing export helps keep that fact on the down low.

2) China is so far behind the West when it comes to these categories that they need to prevent exports to conceal that fact.

3) It's meaningless political gesturing.

So based on the section below, I can add one more possibility:

According to China’s customs data, the US, Vietnam and Singapore were the top-three importers of Chinese aerospace products specified on the list in the first four months of the year.

The US, India and Vietnam were the top-three importers of restricted goods related to gas turbines in the same period. Gas turbines can be used in warships and in large vehicles such as tanks.

The restrictions also cover ultra-high-molecular-weight polyethylene fibre, which can be used for protective equipment such as bulletproof helmets, body armour, bulletproof inserts and bulletproof plates.

Major export destinations for the material between January and April were Brazil, Vietnam, the US and Israel.

There are also restrictions on molds designed to make spacesuit visors, which are likely to affect countries such as Mexico, the US and Vietnam.


Given the US is in the top 3 of importers for these goods, this is a very real supply chain blow to the US.
