AI中文摘要：
隐写术的主要目标是在看似合法的通信消息中传输隐藏消息。然而，相位域信息隐藏尚未在量子系统中得到充分探索。本工作引入了一种基于量子傅里叶变换的有限维量子希尔伯特变换（QHT），作为一种酉相位算子。利用这一构造，我们开发了一种基于QHT的量子隐写方案，该方案将经典比特作为量子载体状态的弱符号相位扰动嵌入。Bob通过二元状态判别、块聚合和经典纠错解码来恢复隐藏消息。
英文摘要：
The main goal of steganography is to transmit hidden messages in legitimate-looking communication messages. Phase-domain information hiding, however, has not been fully explored for quantum systems. This work introduces a finite-dimensional Quantum Hilbert Transform (QHT) as a unitary phase operator based on the Quantum Fourier Transform. Using this construction, we develop a QHT-based quantum steganography scheme that embeds classical bits as weak signed phase perturbations of quantum cover states. Bob recovers the hidden message through binary state discrimination, block aggregation, and classical error-correcting decoding.
