论文摘要
通过研究非量子量子系统中的量子信息掩盖，我们表明可以确定性地掩盖相互正交的量子状态，而在非铁量子量子系统中不能掩盖任意量子状态。我们进一步证明，可以通过伪独立运营商确定掩盖相互吻合的一组线性独立状态。此外，我们研究了针对嘈杂环境的量子信息掩盖的鲁棒性。详细分析了不同量子噪声通道下确定性和概率量子信息掩盖的鲁棒性。因此，我们提出并讨论了多部分系统中的$ r $均匀概率量子信息掩盖。
By studying quantum information masking in non-Hermitian quantum systems, we show that mutually orthogonal quantum states can be deterministically masked, while an arbitrary set of quantum states cannot be masked in non-Hermitian quantum systems. We further demonstrate that a set of linearly independent states which are mutually $η$-orthogonal can be deterministically masked by a pseudo-unitary operator. Moreover, we study robustness of quantum information masking against noisy environments. The robustness of deterministic and probabilistic quantum information masking under different quantum noise channels is analyzed in detail. Accordingly, we propose and discuss the $r$-uniform probabilistic quantum information masking in multipartite systems.
