The spin of an electron placed in a magnetic field provides a natural twolevel system suitable as a qubit in a quantum computer [1]. In this work, we describe the experimental steps we have taken towards using a single electron spin, trapped in a semiconductor quantum dot, as such a spin qubit [2]. The outline is as follows. Section 1 serves as an introduction into quantum computing and quantum dots. Section 2 describes the development of the “hardware” for the spin qubit: a device consisting… CONTINUE READING
