Quantum Connection vs Entanglement: What's the Difference?

Click For Summary

Discussion Overview

The discussion revolves around the terms "quantum connection" and "quantum entanglement," exploring whether they refer to the same concept, their differences, and the prevalence of their usage in literature and media. The scope includes conceptual clarification and terminology in quantum physics.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants express uncertainty about the term "quantum connection," suggesting it may relate to entanglement but lack a clear definition.
  • One participant proposes that "quantum connection" could refer to the quantum coupling of qubits in quantum computing.
  • Several participants note that "quantum entanglement" is a more established and widely recognized term compared to "quantum connection."
  • There is mention of a source that uses "quantum connection," but some participants criticize its validity, suggesting it may be a misinterpretation or a journalistic term.
  • One participant shares a cultural reference, noting that "quantum connection" appears in the Chinese version of a science fiction book but is translated as "quantum entanglement" in English.
  • Some participants highlight that "quantum connection" is not commonly used in the field, with one stating it is the first time they have encountered the term.

Areas of Agreement / Disagreement

Participants generally agree that "quantum entanglement" is a well-defined term, while there is no consensus on the meaning or validity of "quantum connection." Multiple competing views remain regarding its usage and interpretation.

Contextual Notes

Some participants express that the term "quantum connection" may be a mis-translation or a term used by journalists, indicating a lack of formal acceptance in scientific literature.

TL;DR
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?
 
Physics news on Phys.org
"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.

Thanks a lot! Yes, searching Google for Quantum entanglement gives much more hits.

Transmission of information by quantum entanglement​

http://www.journalnano.org/?p=452 (the paragraph below Fig 3)
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.
