Electric field correlation measurements on the electromagnetic vacuum state

Quantum mechanics ascribes to the ground state of the electromagnetic radiation 1 zero-point electric field fluctuations that permeate empty space at all frequencies. No energy can be extracted from the ground state of a system, and therefore these fluctuations cannot be measured directly with an in...
