The impact of weak measurements on quantum characteristics of coupled semiconductor quantum dots system

In our study of super quantum discord between two excitonic qubits inside a coupled semiconductor quantum dots system, our primary focus is to uncover the impact of weak measurement on its quantum characteristics. To achieve this, we analyze how varying the measurement strength x, a?ects this super quantum correlation in the presence of thermal e?ects. Additionally, we assess the e?ect of this variation on the system’s evolution against its associated quantum parameters; external electric ?elds, exciton-exciton dipole interaction energy and Förster interaction. Our ?ndings indicate that adjusting x to smaller values e?ectively enhances super quantum correlation, making weak measurements act as a catalyst. This adjustment ensures its robustness against thermal e?ects while preserving the non-classical attributes of system. Furthermore, our study unveils that the e?ect of weak measurements on this latter surpasses the quantum e?ects associated with the system. Indeed, manipulating the parameter x allows weak measurement to function as a versatile tool for modulating quantum characteristics and controlling exciton-exciton interactions within the coupled semiconductor quantum dots system.
