In this post we will look at three very important things: a theorem that represents a pillar of quantum computing — namely, the impossibility of cloning the states of a qubit; quantum tomography, which allows us to reconstruct the quantum state before the collapse of the wave function; and an application that uses a quantum circuit as a small neural network to approximate a qubit cloner.
