Quantum cellular automata (QCA) is the emerging technology for designing arithmetic and logic circuits at nanoscale. Because of their tremendous cell density, the analysis of the energy behavior of QCA circuits is of great importance. The present study presents a detailed review of how energy is dissipated in QCA cells. For that, two formalisms of the energy behavior of QCA circuits are examined and used to obtain the energy model of the main building blocks in the QCA paradigm. In the first formalism, using the previously developed coherence vector formalism, we propose a complete model for the energy dynamics of the majority voter and wire straight gates. In the second formalism, metal QCA circuits’ energy behavior based on the particle-wave duality of the electrons is proposed. The energy model of the majority voter and wire straight gates in this formalism is compared to that of the first formalism.
