The simplistic tight-binding [1-6] model is used for characterization of mutual electrostatical interaction of  single-electron devices and their interaction with quantum electromagnetic cavity. The presented model is capable in description of electron-electron interaction and electron-cavity interaction as well as quantum electromagnetic cavity-cavity interaction. The emergence of quantum entanglement is traced. The decoherence effects are described. Various concepts of programmable quantum matter in CMOS nanodevices are presented in analytical and in numerical approach with focuss on usage of Berry phase concept [7-9].
