Quantum neuron

The output of classical kth  neuron is:
               
where φ-transfer function depends on θ- threshold and and weights w₀ through w_{m .}

_{In quantum neuron weights are hidden in process of linear supeposition.} 

That is case when these two qubits are not entangled.If they are entangled then their behavior can be described  by the density matrix(operator) <<ρ>>
