A quantum Boltzmann machine (QBM) neuron device is proposed. It consists of a two-dimensional (2D) arrangement of quantum dots that is occupied by quantum-coupled single electrons. The two possible polarizations, “down” and “up,” of the electron spin are used to encode the binary states 0 and 1. The QBM neuron device produces stochastic operations naturally because the electron spin takes the polarization down or up with a certain probability. Calculations for the operation of the QBM neuron device are presented and it is demonstrated that the device can perform the stochastic operations of the BM neuron.
