On a completely different front, let's say the paper completely checks out and they have discovered this miracle. How strong are the patent protections on materials science? For example, if someone could replicate the effect with lead + gold, would that be considered a novel material which would not be subject to licensing? Is it the material itself or the method of production?

I'm sure it depends on jurisdiction, but in the US, you can't patent a material, only a method to make it. If I recall correctly, their patent for method covered a wide range of constituent elements, but left off gold. I would feel pretty bad for them if they genuinely discovered an RTP superconductor but that omission prevents them from becoming billionaires. But more likely the issue is that their current method ha…

Maybe success in life and science isn't about becoming a billionaire?

Even so - if this works out, their prizes and paid speaking gigs will cover a very comfortable life if that's what they want. I'm not sure why they should be entitled to more than that.

So far lab replication efforts are: Two from HUST: https://www.bilibili.com/video/BV14p4y1V7kS/ https://www.bilibili.com/video/BV13k4y1G7i1/ One by USTC https://www.bilibili.com/video/BV1Ex4y1X7ix/ this tiny sample can stand on its pointy side. One by Qufu Normal University https://www.zhihu.com/zvideo/1669820225079070720 One with THU background but claims a personal project https://www.bilibili.com/video/BV14z4y1s7V…

> Why are't more labs outside China making LK-99 and publish videos?

some possibilities:

- they have not been able to conclusively replicate anything and don't want to publish a negative result for fear of someone else publishing a conclusive positive result later.

- they are more careful to publish something that they are not (yet?) 100% sure about

- they don't care so much about the whole 'science in the spotlight' thing and prefer to go the traditional route of publishing after peer review of one or more papers rather than to make YT videos and having to fend off a barrage of interaction

- fear of getting it wrong.

Seems to be the same one that had a video a couple of days ago https://news.ycombinator.com/item?id=36953396 Back then, many asked if this was superconduction or merely diamagnetism. Does the new paper shine any light on this question?

They have quantitative magnetization-versus-temperature data taken using a PPMS (an automated physical property measurement system). It shows strong evidence of some kind of diamagnetic transition at ~ 320K. It seems very likely now that this material has some kind of interesting magnetic property, whether or not it's due to superconductivity.

I hope they're as weak as possible. The worst possible outcome of a room temp superconductor being discovered is stifling innovation to make money off it

I'm generally anti-patent, but if there were any valid case for patents, this is it. Long, hard labor to discover something entirely new that has massive uses for society.

I'd rest my hopes on them not being dicks about it, not on them not getting benefit from it.

Yeah, regular consumer streaming might cover "movies still popular enough but not so new that they're only in theaters." However "all the movies ever made" is a significantly higher bar.

Noob question. Does this breakthrough also translate to advancements in quantum computing? Can we expect quantum computers with far more qbits?

Nope. Quantum computing requires low temperatures not because of resistance but to maintain coherence.

A room temperature superconductor would, by definition, maintain quantum coherence (of the superconducting order parameter) at room temperature.

Yeah, apparently wrong. Not a lawyer, obviously, recovering physicist/current SWE.

I have been SWE for 30 years. My youngest is off to college and I immediately enrolled in a masters program, apparently because I want to understand QFT which no amount of my own reading without doing much homework has enabled.

Even with piracy, it wasn't possible a few decades ago.

If it pans out I'd rather they become billionaires than your average tech bro.
