Abstract

We show that a passing gravitational wave may influence the spin entropy and spin negativity of a system of N massive spin-(1/2) particles, in a way that is characteristic of the radiation. We establish the specific conditions under which this effect may be nonzero. The change in spin entropy and negativity, however, is extremely small. Here, we propose and show that this effect may be amplified through entanglement swapping. Relativistic quantum information theory may have a contribution towards the detection of gravitational waves.
