Generalized electrostatic quantum swap gate implemented in the chain of 2 double coupled quantum dots using single electron in semiconductor is presented in tight-binding simplistic model specifying both analytic and numerical results. The anticorrelation principle coming from Coulomb electrostatic repulsion is exploited in single electron devices. The formation of quantum entanglement is specified and supported by analytical results. The difference between classical and quantum picture is given. The correlations between geometry of quantum structures and entanglement dynamics are shown in analytical way. Effective wavefunction of single electrons is extracted from 2 electron electrostatic interactions. The presented results have its significance in cryogenic CMOS quantum technologies that gives perspective of implementation of semiconductor quantum computer on massive scale.
