    is a key resource for quantum technologies, including emerging ground-to-satellite
    quantum communication. In such a scenario, an important challenge to be overcome
    is to consider entanglement between two or more quantum particles in different
    inertial frames, potentially experiencing relativistic effects affecting quantum
    correlations. In this paper, we present a consistent framework that overcomes
    this challenge. To this end, we establish the notion of factorizable and entangled
    multi-time trajectories and derive a class of Euler–Lagrange equations under the
    constraint of a non-entangling behavior. Comparing this restricted evolution to
    the solutions of the unrestricted equations of motion allows us to investigate
    the trajectory-based entanglement of general systems. We solve our equations for
    interacting particles in a Klein–Gordon-type setting, thereby quantifying the
    dynamic and relativistic impact of entanglement in a self-consistent manner.</jats:p>@eng"
