【Abstract】 Objective: To investigate the protection of multipartite quantum steering in open systems based on quantum measurements techniques. Methods: Optimal measurement outcome for protecting multipartite quantum steering is obtained by employing a combination of quantum reversal measurement and quantum weak measurement. Results: In the absence of measurements, multipartite quantum steering gradually degrades under the influence of decoherence effects until it vanishes. However, with the optimal measurement outcome, multipartite quantum steering gradually recovers as the measurement intensity increases. Conclusion: Quantum weak measurement can effectively protect multipartite quantum steering from degradation due to decoherence effects in open systems.更多还原
