Decoherence and disentanglement of qubits detecting scalar fields in an expanded spacetime
Abstract We consider Unruh–Wald qubit detector model adopted for the far future region of an exactly solvable $$1+1$$ 1 + 1 dimensional scalar field theory in a toy model of Robertson–Walker expanding spacetime. It is shown that the expansion of the spacetime in its history enhances the decoherence...
