Quantum information masking in non-Hermitian systems and robustness

By studying quantum information masking in non-Hermitian systems, we show that mutually orthogonal states can be deterministically masked, while an arbitrary set of cannot masked systems. We further demonstrate a linearly independent which are $\eta$-orthogonal by pseudo-unitary operator. Moreover, study robustness against noisy environments. The deterministic and probabilistic under different noise channels is analyzed detail. Accordingly, propose discuss the $r$-uniform multipartite
