Existing work focused on pre-entangled states or Markovian baths, leaving open whether separable squeezed inputs entangle in structured environments or under modulation. We study two bosonic modes coupled to a common reservoir, each initialized in a separable squeezed vacuum. Dynamics are analyzed utilizing Gaussian covariance methods, evolved under approximate Non-Markovian quantum state diffusion (QSD), finite-temperature pseudomode embeddings, and Bures-"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"Three mechanisms absent in Markovian dynamics are identified: a detuning condition that freezes entanglement trajectories across reservoir correlation times; birth, death, and revival of entanglement from orthogonal inputs; and integer-locked beating with square-wave oscillations produced by periodic detuning.
