Vacuum flucutuations = local entanglement between quantum fields?
I'm puzzled by this statement by Dieter Zeh: "Various types of quantum fluctuations (in particular vacuum fluctuations, often visualized in terms of 'virtual particles') are used to describe ...

Is it possible to peform thermodynamic work by harvesting entanglement from the vacuum?
I have already asked two questions on this topic:
1. What happens to the vacuum when entanglement is harvested? [closed]
and
2. Does entanglement harvesting require cooling the environment to ...

What happens to the vacuum when entanglement is harvested?
I stumbled upon this website which talks about entanglement harvesting. I also already asked a question on this subject regarding some experimental question. In this post I want to ask another ...

Does entanglement harvesting require cooling the environment to sufficiently low temperatures?
I stumbled upon this webpage, which describe a process they call "entanglement harvesting". I was wondering whether to observe this effect it is necessary to cool the environment to ...

QFT: the origin of vacuum correlation
My question is about the origin (or mechanism?) of vacuum correlation.
In quantum field theory in flat spacetime, a free scalar field has the following two-point correlation function at the same ...

Physical interpretation of entanglement in QFT vacuum
The ground state of a relativistic QFT has nonzero
correlation between field operators at spatially separated points. A way to interpret this is through entanglement between different spacetime ...

Is there an intuitive description of vacuum entanglement?
People often refer to the fact that the vacuum is an entangled state (It's even described as a maximally entangled state).
I was trying to get a feeling for what that really means. The problem is ...
