[louislaolu]

TL;DR Summary

quantum connection vs. quantum entanglement
different or the same?

quantum connection vs. quantum entanglement
Do they mean the same?
Are there any differences?
Is the second one more common/newer/more standard than the first one?
Could someone please answer these questions or recommend something to read?

"Quantum connection" seems vague to me. It would have some relation to entanglement but I have no idea with confidence what it is. I would take it as quantum coupling of two qubits and using them as one system for quantum computing.　Quantum entanglement is more established term as you can find some explanation in wiki or other sources.

This is not a valid source for discussion here. The paragraph below figure 3 is wrong in any case. Journalists aren't physicists!

I actually came across 量子联系 (literally translated as quantum connection ) in the Chinese version of the science fiction The Three Body Problem. It was changed into quantum entanglement in the English version. I am trying to figure out the change.

"Quantum connection" is not a widely used term (in fact, it is the first time I've seen it and I've been doing this for quite a while), it sounds either like a journalist trying to be clever with his/her choice of words, or a mis-translation.
"Quantum entanglement" is a widely used, well defined term

Thank you for your reply! It helps me a lot.
