dc.description.abstract-translatedWe analyze an adaptive two-qubit purification protocol based on DEJMPS filtering for Bell pairs subject to combined amplitude- and phase-damping noise. A precomputed lookup table selects the optimal purification depth d and filter strength α according to real-time single-qubit channel estimates (ˆγ, ˆp). Monte Carlo simulations (T =500 trials per (γ,p) grid point) over a 20×20 noise parameter sweep reveal that adaptivity yields nonzero f idelity gains ∆F > 0 at a few, with an average positive ∆F ≈ 0.83 at those points. These fidelity improvements occur in highly localized "islands" of moderate to high noise, and always incur a half-yield penalty ∆Y = 0.5. We present 3D surfaces and 2D contour maps of ∆F(γ,p) and ∆Y(γ,p), alongside a representative table of the (γ,p) pairs with ∆F ̸ = 0. Our results demonstrate that adaptivity provides significant fidelity boosts only in select noise regimes, informing when to trigger adaptive purification in practical quantum repeater and QKD deployments.en
