First "Quantum Entangled" Animal in History

Not sure where this might lead to. Can it be scaled up for a Star trek transporter?

Frozen tardigrade becomes first 'quantum entangled' animal in history, researchers claim

researchers have exposed tardigrades to the coldest temperatures and highest pressures that moss piglets have ever survived — not just to test the critters' biological limits, but also to see whether a frozen tardigrade could be incorporated into two quantum entangled electric circuits, then later revived to its normal active state.

The results, reported in a new paper published to the preprint database arXiv, suggest that, yes — scientists may be able to add "temporary quantum entanglement" to the tardigrade's growing list of accomplishments. However, early responses to the paper have taken issue with this finding.

If the findings ultimately withstand peer review, then this experiment will represent the first time a living animal has been quantum entangled — a bizarre phenomenon typically confined to the smallest subatomic particles.

One reason why a Star Trek transporter isn't really ever going to be practically achievable is the sheer amount of information necessary to fully describe even just a single cell, never mind an entire person.

I recently heard an estimate that it would take 4,850 trillion years to transmit enough information to reproduce a single human body cell.

https://en.wikipedia.org/wiki/Transporter_(Star_Trek)#Real-world_feasibility

Physics students at University of Leicester calculated that to "beam up" just the genetic information of a single human cell (not the positions of the atoms, just the gene sequences) together with a "brain state" would take 4,850 trillion years assuming a 30 gigahertz microwave bandwidth.[9]

Even assuming we improve our information storage and transmission bandwidth capabilities, we have a long, long way to go.

I wouldn't say it's impossible in principle; just not practically achievable before we go extinct as a species.

I've known that for a long time. I should not have introduced ST. This transporter would work on spooky action at a distance quantum effects. (for weak definitions of "would" and "work".)

I don't expect to see corrections by the mainstream media. However, the general public is too busy paying attention to the crap that spews forth from celebrities, so it doesn't matter anyway.

I’m sure that some homeopath, somewhere, will be claiming that this means that homeopathy works.

Well this is extremely disappointing:

Despite very misleading language, the authors of this paper haven't achieved (2) (let alone (1)!)

Instead, they've shown (3): a *classical* interaction between the qubit and tardigrade.

And right after I had heavily invested in the technology too.

Man, those crazy tardigrades, is there nothing they can't do?

I don't trust them - they tried to eat Ant-Man.

640KB is more than enough memory for any computer /s

That's what they said about the telephone.

Only if you need an exact copy. We don't do this with anything else we copy, so why does this case have to be different? The answer is, it doesn't.

Imagine you had a transporter that didn't make an exact copy of the original body, but simply transferred the person's mind (only ~2.5 petabytes of data) into another one. Nice new bodies could be 'cloned' off their DNA (~3 billion bytes of data required) and 3d printed just in time for the transfer. The new body wouldn't be identical to the old one, but would anyone care? Of course they would. People would be transporting themselves into the same room just to get a new body!

I beg to differ. If the insides of your cells are scrambled up, you won't be able to live.

Imagine you had a transporter that didn't make an exact copy of the original body, but simply transferred the person's mind (only ~2.5 petabytes of data) into another one.

But what, exactly is a "mind" for this purpose? Will you retain your memories? Will it still be you on the other side, or something more like your identical twin? A different person with a similar body.

If it doesn't have to be an exact copy, does that mean that identical twins are actually only just one person with two different bodies?

Nice new bodies could be 'cloned' off their DNA (~3 billion bytes of data required) and 3d printed just in time for the transfer.

I don't think you can 3d print a living body. It isn't like a brick. Some sort of uniform substance. Bricks are fungible, assuming they are all made with the same materials and method. The insides of human body cells are incredibly complex. And they all have to be functional, or at least most of them do. It takes approximately 20 years to grow an adult human body.

The new body wouldn't be identical to the old one, but would anyone care? Of course they would. People would be transporting themselves into the same room just to get a new body!

I'll believe it when I see it.

Perhaps if it could be programmed to say, “what?” and, “I don’t understand” and, “where’s the tea?”, nobody would notice the difference.

 

[Jack by the hedge]

Did they keep watching the experiment after it finished? I worry they missed the part where the good tardigrade's evil twin appears too.

I'd notice the difference!

Sure you need functioning cells, but they don’t need to be in exactly the same places or even of exactly the same numbers. I think if you could swap just the brains of identical twins they would be fine, hardy notice the difference.
You probably just need a functional body with your mind in and everything wired up correctly. Something generic will be fine, you can get used to different proportions and things. Also who wants a new body exactly like the stupid old one.

I But what, exactly is a "mind" for this purpose? Will you retain your memories? Will it still be you on the other side, or something more like your identical twin? A different person with a similar body.

In my opinion your mind, memories included, resides in the architecture and connection strengths of the neural network of your brain. I think you would still feel like yourself even if you were a disembodied simulation of your personal ‘mind network’ running on whatever hardware.

If it doesn't have to be an exact copy, does that mean that identical twins are actually only just one person with two different bodies

No, they each have totally unique minds and bodies and biochemistries. They just look and sound very similar.

No you wouldn’t, you would be programmed not to.
