# Quantum transformation equivalent to Discrete Wavelet transform

Suppose we have a matrix $$A=\begin{bmatrix} 2 &4 \\ 1 & 4\\ \end{bmatrix}$$, when applying the discrete wavelet transform to this matrix we get 4 parts i.e smooth part ($$1\times 1$$) matrix, 3 detail parts each of them being ($$1\times 1$$) matrices. Is there any quantum transformation that performs this task? Can somebody suggest? Is it in some way related to Fourier Transformation?

• Could you expand a bit more? Apr 8 '19 at 15:47
• what part do you want me to expand? Apr 8 '19 at 16:39
• You seem to be using non-standard terminology with detail parts etc so follow through with your example A. Apr 8 '19 at 18:49
