Multiple Unruh-DeWitt detectors harvest more vacuum entanglement when arranged in specific configurations, with harvested negativity scaling linearly in linear chains.
In particular, we compute the leading-order neg- ativity for different spatial arrangements as a function of the distancelbetween subsystemsAandB
