The concept of an Ansible, yes? But it requires taking one half of the entangled pair(s) physically away to the second location.Scott Rowe– Scott Rowe2024-12-23 13:33:12 +00:00Commented Dec 23, 2024 at 13:33

1@ScottRowe Sorry, don't know about Ansible. Encryption needs a common shared key that is transmitted from A to B. If you ensure that the signal consists of entangled particles, eg polarised photons, then you can avoid interception as interception necessarily is a measurement and thus collapses the quantum state, i.e. the entanglement. The Chinese did a successful experiment in 2020 that sent entangled particles from a satellite to three cities over 1200 kilometers. According to some people this could lead to an unhackable 'quantum internet'. Anyway, I am not an expert and don't claim to be onePhilomath– Philomath2024-12-23 14:05:44 +00:00Commented Dec 23, 2024 at 14:05

1@ScottRowe Ah, I see, no it is in fact, un-ansible. Nothing to do with faster-than-light.Philomath– Philomath2024-12-23 15:11:53 +00:00Commented Dec 23, 2024 at 15:11

How to Edit
- Correct minor typos or mistakes
- Clarify meaning without changing it
- Add related resources or links
- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
-
create code fences with backticks ` or tildes ~
```
like so
``` -
add language identifier to highlight code
```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- quote by placing > at start of line
- to make links (use https whenever possible)
<https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. philosophy-of-science), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
