Abstract
Nanowires modulated with quantum dots temporally holds the electron with desired spin direction with the external magnetic field. A single quantum dot can hold any number of electrons and each electron within dot stores the qubit of information. Spin of electron and orientation of electron spin with applied field are the qubit of information stored within quantum dots. Reading of spin is done by tunneling the electron to the common region where spin nutation and superposition of two different spin occurs. Spin nutation also results in spin exchange or quantum entanglement between two or more electron spin of two neighbouring dots at the common region within lattice of nanowire. Spin direction in quantum dot is detected by the spin detector converting spin direction of spin to the charge of electron within quantum dot. At the common region spin orientation and direction of entangled spin is computed by the Hamiltonian operation of entangled spins.
