Abstract
The reliable transmission of quantum information remains a central challenge in the presence of environmental noise. In particular, maintaining high teleportation fidelity in open quantum systems is hindered by decoherence, which disrupts quantum coherence and entanglement. Traditional noise-mitigation approaches usually overlook the temporal correlations that exist in realistic environments. This naturally raises a question: can we exploit non-Markovian memory effects to enhance quantum teleportation performance? In this work, we address this problem by analyzing how non-Markovian dynamics influence teleportation fidelity. We employ a statistical speed approach based on the Hilbert–Schmidt norm to witness information backflow and monitor the system’s instantaneous evolution rate. Our study focuses on two measurement-based strategies: weak measurement combined with quantum measurement reversal (QMR) and a hybrid protocol integrating environment-assisted measurement (EAM) with post-selection and QMR. Through analytical expressions and detailed numerical simulations, we demonstrate that both strategies can enhance teleportation fidelity under non-Markovian noise. Notably, the EAM-based scheme exhibits superior robustness, achieving high fidelity even without fine-tuned parameters. Our results establish a concrete link between non-Markovian memory effects, statistical speed, and coherence preservation, offering practical insights for the design of resilient quantum communication protocols.
