This review describes recent groundbreaking results in Si, Si/SiGe, and dopant-based
quantum dots, and it highlights the remarkable advances in Si-based quantum physics that …

We investigate the quantum dynamics of a Cooper-pair box with a superconducting loop in
the presence of a nonclassical microwave field. We demonstrate the existence of Rabi …

We consider a single electron in a 1D quantum dot with a static slanting Zeeman field. By
combining the spin and orbital degrees of freedom of the electron, an effective quantum two …

justification, could be called the micro electronics era. During that 50-year pe riod, the world
witnessed a revolution based on a digital logic of electrons. From the earliest transistor to the …

The thermal entanglement in a two-qubit Heisenberg XXZ spin chain is investigated under
an inhomogeneous magnetic field b. We show that the ground-state entanglement is …

We review several proposed spintronic devices that can provide new functionality or
improve available functions of electronic devices. In particular, we discuss a high mobility …

We theoretically consider coherence times for spins in two quantum computer architectures,
where the qubit is the spin of an electron bound to a P donor impurity in Si or within a GaAs …

We study the effect of inhomogeneities in the magnetic field on the thermal entanglement of
a two-spin system. We show that in the ferromagnetic case a very small inhomogeneity is …

We study the bipartite entanglement dynamics in an anisotropic two-qubit Heisenberg XYZ
model under the influence of population relaxation and in the presence of various types of …

We study the effect of the spin-orbit interaction on quantum gate operations based on the
spin exchange coupling where the qubit is represented by the electron spin in a quantum …
