خصائص نقل الإلكترون لكيوبت مقترن بترانزستور الإلكترون المفرد : حساب أعداد إشغال النقاط الكمية و التيار في حالتي الاتزان و اللاإتزان

Abstract EN

In this study, theoretical treatment is presented to study the electron transport for a system consists of two principle coupled parts, these are the key element of quantum computer which is represented by the qubit and the detector which is represented by the single electron transistor.

Model calculation that includes the derivatives of the time dependent equations of motion for the system under consideration is presented.

We find particular relations for the time variation for of the occupation numbers of the qubit quantum dots and the single electron transistor dot as well as the current that flows from the left lead.

We investigated the electron transport dynamical properties in the system at equilibrium and nonequilibrium.

We conclude that the charge accumulation increases on the far-removed qubit quantum dot from the single electron transistor as the bias voltage decreases and vice versa.
