Abstract

We have presented extensive and nonextensive entropy of RbCl quantum well qubits (QWQ). To this end, we have considered an electron that is coupled to the LO-phonon in RbCl quantum well to determine the energy eigenvalues and eigenfunctions of the ground and first excited states of the system using the Pekar variational method. Here, we have used extensive and nonextensive entropies like Shannon and Tsallis to study decoherence of RbCl QWQ for different parameters. Our results show that the entropies have the oscillatory periodic evolution as a function of time due to the form of the confinement potential. According to the obtained results, we can see that the entropies oscillate under a sinusoidal envelope with enhancing the confinement parameters. These results may be very helpful in the transmission of information in the nanostructure.
