Even the most sophisticated artificial neural networks are built by aggregating substantially identical units called neurons. A neuron receives multiple signals, internally combines them, and applies a non-linear function to resulting weighted sum. Several attempts generalize neurons quantum regime have been proposed, but all proposals collided with difficulty of implementing activation functions, which is essential for classical neurons, due linear nature mechanics.

Quantum computers have the potential of solving certain problems exponentially faster than classical computers. Recently, Harrow, Hassidim and Lloyd proposed a quantum algorithm for linear systems equations: given an $N\times{N}$ matrix $A$ vector $\vec b$, find x$ that satisfies $A\vec x = \vec b$. It has been shown using one could obtain solution encoded in state $|x$ $O(\log{N})$ operations, while algorithms require at least O(N) steps. If is not interested $\vec{x}$ itself but...
