Quantum algorithms can enhance machine learning in different aspects. The quantum support vector was proposed to improve the performance, which Swap Test plays a crucial role realizing classification. However, as is destructive, must be repeated preparing qubits and manipulating operations. This paper proposes based on amplitude estimation (AE-QSVM) gets rid of constraint repetitive process sav...

Most of the existing color image watermarking schemes were designed to mark the image luminance component only, which have some disadvantages: (i) they are sensitive to color attacks because of ignoring the correlation between different color channels, (ii) they are always not robust to geometric distortions for neglecting the watermark desynchronization. It is a challenging work to design a ro...
