Quantum Neuron: an elementary building block for machine learning on quantum computers

  title={Quantum Neuron: an elementary building block for machine learning on quantum computers},
  author={Yudong Cao and G. Guerreschi and Al{\'a}n Aspuru-Guzik},
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 the resulting weighted sum. Several attempts to generalize neurons to the quantum regime have been proposed, but all proposals collided with the difficulty of implementing non-linear activation functions, which is essential for classical neurons, due to the linear nature of… Expand
