While the teleportation is instantaneous, I don't think there's any way to bypass the need for ancilla to be transported "classically," which are required for the Bell measurements at the receiver.
And there's still the causality problem (manifest here as "information causality" - PDF). Of course, one should never say never, but it seems there's always a fundamental roadblock when it comes to FTL, regardless of the path taken.

Thanks for having a crack, that article is a touch over my head as well, but I have found this article which explains an abiotic process for ethanol synthesis, which may not be the one that is happening on the observed planet, but at least I now know that ethanol is possible to be synthesised by abiotic means, whereas when I initially read the OP I was thinking they found sure signs of life for a minute there!

Idk about that, I'm leaning towards random chance. That said, I don't prescribe to religious beliefs and don't remember any character selection...

I do understand this a bit different and would expect that this would be actually possible. According to the relativity theory the point is that the "spooky entaglement" happens at identical times everywhere.
Maybe this paper is better:
https://jqi.umd.edu/news/first-teleportation-between-distant-atoms
or this
"teleportation" is in my understanding "timeless" as it happens between entagled entities.

My understanding here is that the ancilla are themselves limited by the speed of light, thus limiting communication speed to the same, and this experiment's goal was to (dis)prove the apparent instant simultaneous collapse. But I'm very open to correction here.

Here are some of the best models we have of Jupiter's near-core:
https://arxiv.org/pdf/1812.07436.pdf
p12 allows for both a sharp discontinuity and a gradual 'fade' from metallic hydrogen to rock. The data we have cannot distinguish between those models.
"The existence of a diluted core, or a steep heavy-element gradient inside Jupiter is actually consistent with formation models of Jupiter (see section 4.3 for details). Giant planet formation models in the core accretion scenario (e.g., Pollack et al., 1996) suggest that once the core mass reaches ∼ 1 − 2M⊕ the accreted solid material (heavy elements) vaporise and remain in the planetary envelope (e.g., Stevenson, 1982). This leads to a structure in which the deep interior is highly enriched with heavy-elements, with no sharp transition between the core and the inner envelope (e.g., Helled & Stevenson, 2017 and references therein)."

My understanding of
In the second part of the paper, Schrödinger showed that an experimenter, by a suitable choice of operations carried out on one member of an entangled pair, possibly using additional ‘ancilla’ or helper particles, can ‘steer’ the second system into a chosen mixture of quantum states, with a probability distribution that depends on the entangled state.
Is that actually you can change one system by changing the other.

This is very interesting. Does anyone know if it requires activation on mobile phones or if it's automatic.

I wonder if there are layers before the core that have some amounts of solids settled in above higher density gases. So not that it’s a surface but that it’s a layer of solid (even if it’s a dusty consistency) above denser gases

If you snort it you can fold space.
