报告摘要：

Conditional non-Hermitian dynamics encodes information not only in the normalized quantum state, but also in global norm and phase variations, which together constitute an otherwise hidden global non-Hermitian effect (GNHE).

In this talk, I will show how a reference-mode embedding reveals the operational information structure underlying GNHE, with quantum geometry and residual yield jointly determining the attainable precision under fixed total resources, and how information flow governs the evolution of this structure, revealing the interplay between geometric and residual-yield contributions.

This framework may open a new avenue for investigating conditional non-Hermitian dynamics and controlling fixed-resource precision through its underlying information structure.
