We examine a class of bipartite mixed states which we call X states and report several analytic results related to the occurrence of so-called entanglement sudden death (ESD) under time evolution in the presence of common types of environmental noise. Avoidance of sudden death by application of purely local operations is shown to be feasible in some cases.

  1. Anomalous Decay of Quantum Resources: The Entanglement Sudden Death Mpemba Effect

    quant-ph 2026-05 unverdicted novelty 6.0 of 10

    More strongly entangled two-qubit states can reach separability faster than weakly entangled ones under local amplitude damping, forming an ESD Mpemba effect with an exact analytical derivation of crossover time.

  2. Entanglement Harvesting and Quantum Discord of Alpha Vacua in de Sitter Space

    hep-th 2024-06 unverdicted novelty 6.0 of 10

    The reduced states of static UDW detectors coupled to a scalar field in alpha-vacua are derived analytically, revealing distinct behaviors of entanglement harvesting for time-like versus space-like separations and sup...

  3. Manipulating Bell nonlocality and entanglement in polarized electron-positron annihilation

    hep-ph 2026-02 conditional novelty 5.0 of 10

    Polarized lepton beams can tune hyperon-antihyperon entanglement and Bell nonlocality, with transverse polarization capable of producing maximally entangled pairs.

  4. Local-available quantum correlation swapping in one-parameter X states

    quant-ph 2025-07 reject novelty 5.0 of 10

    LAQC can be redistributed by projective swapping in X states, but the paper's key examples claiming separable final states with nonzero LAQC are only valid for part of the parameter space.
