FTL Communications?

Except it is two-way communication. When the "orders" are "opened", it "sends" a signal back to the original particle. Then the commander knows if the orders have been received or not. Also, are you taking retrocausality into account?
How would they know? The spin detected is random and so meaningless on its own.

"We measured the spin so its changed on the other end. Wait ten seconds for them to respond and measure it again."

"It's spinning down, sir. What does that mean?"

"I have no idea."

I doubt either of us have enough of a quantum physics background to really debate this, so I'll leave it to the sources cited. Which say information is still constrained by light speed.

If you have serious academic qualifications in this field, I apologise.

My firsthand knowledge of this is from too long ago to matter., so take it with a dump truck full of salt. I haven't been active in the field since college, but I am aware of no math that says that information is constrained by the speed of light, methods of transmitting that information, yes, but the actual information itself, not unless there is something new in the last 30+ years in relation to this that I am unaware of.

It can't be random if they can use it for doing calculations. If it is truly random, then you cannot have a logicgate, but this "computer" does, separated by 6 feet of space. Our understanding of this science is still quite limited, but some things must be true in order for it to be used for quantum computing.

Ah.

You're conflating information with data. Easy to do.

Data can exist unobserved, but information requires observation, and thus is constrained by relativity.

If the sun explodes, that event is data, but until I become aware of it, it cannot be information to me.

I’m no expert in this, but the qbits are in close proximity and the information can be passed back and sense made of the calculations.

All I know for sure is that the experts says no information can be sent. That’s good enough for me.

Ahhh! Okay. You are correct. That is My issue. Thank you for helping Me understand that better. :)

Yeah. I am out of My depth as well. I just liked the article and found it interesting.
 
Here is a link.

So, basically, the information is transmitted faster than light, but since We can't understand it until we are told when to measure it, it is still limited by slower than light communication.

Edit - btw... Nice article. Thanks for sharing it.

This is one of the major arguments in physics, and most get it wrong, fortunatel another video just dropped that will help:

Retrocausality is proof that we have no understanding of what is happening in the real world when we apply quantum maths. It leads to paradox.

It arises from our limited knowledg of locality vs non-locality and real vs virtual.

They are entangled, if you know the spin of one of them you know the spin of both... but
"We measured the spin so its changed on the other end. Wait ten seconds for them to respond and measure it again."
The act of observation or measurement breaks entanglement, as soon as you obsevre partice 1 tou know the properties of particle 2 but they are no longer "entangled" entangled.
"It's spinning down, sir. What does that mean?"
It means the other is "up", but since from your point of view it is random you can't send information this way.
"I have no idea."
Sums up our current understanding of how it all works, we know it does, we just don't know how.

What change of state? From not entangled to entangled? The entanglement process takes time.
The change of one of the linked pair changing spin if the other is measured. Like I said, I know very little about this and could be completely wrong.
 
As a pretty salient point, Traveller does have FTL communication. It just requires Jumpspace and at the usual TLs, a ship.

IMHO, the most Traveller-ish way to handle it at higher TLs would be some kind of Jumpspace radio, that can send and receive messages that take 7 days to arrive. Possibly having less range than the J-Drive of the same TL.

If you want to go that route. Use the Hop Drive TL progression for your jumpspace radio's range. As long as it still takes a week for the message to get there, then it wouldn't break the setting.

TL-17 1 parsec
TL-18 2 parsecs
TL-19 3 parsecs
etc.
