In this work, we present a quantum information framework for the entanglementbehavior of the low energy quasiparticle (QP) excitations in various quantumphases in one-dimensional (1D) systems. We first establish an exactcorrespondence between the correlation matrix and the QP entanglementHamiltonian for free fermions and find an extended in-gap state in the QPentanglement Hamiltonian as a consequence of the position uncertainty of theQP. A more general understanding of such an in-gap state can be extended to aKramers theorem for the QP entanglement Hamiltonian, which also applies tostrongly interacting systems. Further, we present a set of ubiquitousentanglement spectrum features, dubbed entanglement fragmentation, conditionalmutual information, and measurement induced non-local entanglement for QPs in1D symmetry protected topological phases. Our result thus provides a newframework to identify different phases of matter in terms of their QPentanglement.
