SUMMARY:

Studying Quantum dynamics and effectively investigating forms to keep quantum properties are completely necessary to turn possible new applications in Quantum Mechanics.Through this work quantum dynamics with stochastic reset was studied for Quantum Harmonic Oscillator and the Jaynes-Cummings model in order to understand possible ways to reduce decoherence
caused by the interaction between the system and environment.The main goal was to analyze if stochastic reset contributes to maintaining the quantum properties of the system. The intention was to research ways to keep quantum properties in the direction of enabling dynamics that, in principle, could not be applied in quantum technologies due to decoherence, becoming applicable. To achieve this goal, through this work we studied Quantum Dynamics with reset for Quantum Harmonic Oscillator and, also the Jaynes-Cummings Model with and without dispersity. An analysis of the purity of the studied
physical systems was made considering the density matrix and its properties, mainly, regarding the trace, the linear entropy, and the nonclassicality of the state dynamics of the Jaynes-Cummings model under stochastic reset was made considering the roughness of a quantum state as a measure of the quantumness.
