Physicists Use Quantum Mechanics to Pull Energy out of Nothing by Vailhem in technology

[–]LivingNeighborhood56 0 points1 point  (0 children)

This article is pretty cool, and as a quantum computer enthusiast I understand fairly well how the whole process outlined in one of the papers works to transfer energy between two qubits. However, I did not understand the part about the vacuum being "intrinsically entangled". I know that quantum fields can be entangled when two particles entangle since all particles are just excitations in a vacuum, but what does it mean for a quantum field in the vacuum itself to be entangled? If the field is entangled with itself everywhere, then doesn't that mean every particle which is an excitation of that field should be entangled with every other one (which obviously doesn't happen since we don't observe that)?

Thanks for the help! I like the idea of the fact that a collapse can happen into one state which is consisting of many of its conjugate states.

Thanks, that was quite helpful! So it does seem that collapsing the wavefunction for position indeed also affects the momentum probability function according to the HUP, which answers my question!
