Stability of Bi-Partite Correlations in Symmetric N-Qubit States Under Deterministic Measurements

Year: 2025

Type: article

Abstract: In this paper, we analyze the distribution of bi-partite correlations in pure symmetric N-qubit states during local deterministic measurements, which ensure the same value of the reduced purities in the outcome states. It is analytically shown that all reduced purities grow in the process of deterministic measurements. This allows us to characterize the stability of bi-partite entanglement during the optimal correlation transfer under single-qubit measurements in the asymptotic limit N≫1.
