Information Entropy of Nanostructure systems

Systems based on quantum-dot nanostructures could be used as components for quantum information
processing devices. One of the possible advantages of the use of quantum dots is that the parameters of the
system may be changed, allowing the properties of semiconductor nanostructures to be tailored. The
seemingly inexorable progress of technology appears to promise advanced engineering of quantum dot
based structures, thus leading to the fabrication of coupled and scalable quantum dot systems. To use
quantum dot devices for quantum computing necessitates the ability to generate and manipulate
entanglement within these structures. Using Supersymmetric Quantum mechanics, isospectral Hamiltonian
approach is utilized to calculate the information entropy of the isospectral potential which contains a free
parameter. This free parameter can be adjusted to model the complex nanostructure materials and
therefore to calculate their entanglement degree.
