Overview of affine transformation based on QOT. (a) The flow chart of 2-dimensional affine transformation. First, Alice prepares input \(\vec {x}\) and Bob prepares A and \(\vec {b}\). Then the matrices are scaled so that the norms of matrices are lower than 1, and are sampled as input binary matrices. The secure affine transformation is conducted through encoding and encoded operations based on QOT. (b) The diagram of encoded AND gate implementation based on QOT. Trent sends entangled pairs. Alice and Bob perform the encoded AND by transmitting the indices. (c) The quantum circuit for Trent to prepare entangled pairs.
