Transferred from what to what? Is there any memory or storage media that has I/O fast enough to say you actually transferred any information?

DDR5 is 50GB/s, which is workable. But it's possible there'll be a way to apply this technology to get even better throughput on memory and processors as well.

EDIT: Here's a thought. Mosix, the software that allowed pooling processors from multiple separate computers together over a network always had the issue that the network was too slow to properly copy memory around fast enough. With this kind of transfer speed it's actually practical to stream memory from one machine for processing on another.

From point A to point B, in a lab under laboratory conditions. There's no need for storage or memory, because all that's being measured is data flow.

This is a very interesting experiment that could have implications for switches in massive data centers, but isn't all that useful for anyone here.

I'm sad that redditors in this sub seem to not understand even a little what this article is saying, given that what's being described (data transmission) is pretty basic technology. What's new is the technique and hardware.

First, fuck off with your condescending tone. Fuck right off with it.

Second, what did they transmit from point A to point B? If it's actual data, then in order to confirm that what you think you sent from point A to point B is what actually got sent, without appreciable loss, you would need to check the data. Via a checksum or something. I'm asking how that's done.

If they didn't do that, then I don't see how one can claim any data was sent. It sounds to me like they sent noise at that point.

By no means do I understand the details, but I have to imagine they are only sending a very small amount of data, such that the chip itself is able to locally store the information and release it at a speed the next layer of hardware is capable of handling.

Thanks for your insight. That would make sense to me, and perhaps then they simply sent that data many multiples of times in that short span to add up to the petabytes they're quoting. Or maybe they simply sent a tone over each of the channels and used that as a proof of concept that they could have sent those petabytes.

In any case, I'm still curious about what information actually was transmitted.
