Abstract
We propose an experimental method for extracting the zero-point energy from a local vacuum state by performing local operations and classical communication (LOCC). We model a quantum Hall edge channel as a quantum entangled many-body channel and the zero-point fluctuation in the charge density of the channel as the vacuum state. We estimate the order of the energy gain using reasonable experimental parameters. Such a quantum feedback system breaks the passivity of a local vacuum state. It can be used to demonstrate Maxwell's demon or quantum energy teleportation in which no physical entity transports energy.
