The electron transport properties of qubit coupled with SET : the tuning of the qubit energy levels

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.

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 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.

Perfect quantum measurement can be obtained through the initialization and manipulation processes which are intended the system initialization and manipulation before the start measurement process and through the control of the parameters, the important parameters connected the electrical structure of sub device.

The most important use gate voltage to tunning the qubit energy levels
