图像压缩与纠缠

Image compression and entanglement

Jose I. Latorre

摘要:

图像的像素值可以使用适当的块结构化寻址被转换到希尔伯特空间的实数ket中。由此产生的状态,然后可以重写其矩阵乘积状态表示的方式,量子纠缠对应于不同的粗粒度纹理之间的经典相关性。MPS表示的截断等同于原始图像的压缩。该算法可以通过增加离散傅立叶变换预处理和进一步的熵无损压缩来改进。

英文摘要:

The pixel values of an image can be casted into a real ket of a Hilbert space using an appropriate block structured addressing. The resulting state can then be rewritten in terms of its matrix product state representation in such a way that quantum entanglement corresponds to classical correlations between different coarse-grained textures. A truncation of the MPS representation is tantamount to a compression of the original image. The resulting algorithm can be improved adding a discrete Fourier transform preprocessing and a further entropic lossless compression.
