Throughout this thesis, I have underlined the potentials of the bound electron in ZnSe:F system by experimentally demonstrating some of the demanded properties as qubits. In Chapter 3, I introduced the QW-confinement for an enhanced optical brightness and a reduction of the inhomogeneous broadening. An increased binding energy of exciton was also observed due to the compression of the donor wavefunction in the QWs. In Chapter 4, we have investigated conventional MBE fluorine doping method and reported a limitation of reaching the demanded doping level. Thus, we installed the ZnF2 cracker cell to establish 19F molecular beam flux. As a result, we were able to modulate the doping level between 1E15 cm-3 and 1E18 cm-3 by doping temperature and mode. Alternatively, we have investigated the ion implantation of fluorine in ZnSe QWs, and reported that the fluorine impurities can be incorporated as active donors. In the following chapter, I provided fabrication processes of ZnMgSe/ZnSe pillars as means of isolating individual fluorine impurities. The photoluminescence spectroscopy from F-implanted pillars was also investigated in Chapter 5. In Chapter 6, under an external magnetic field, we have verified the presence of optically controllable lambda-system, which is fully-connected, and initializable. Although there are still several advancements to be made to verge on other candidate systems as reliable qubits, based on the works presented in this thesis and further potentials to be realized, the ZnSe:F system remains as an appealing solid-state based qubit candidate for quantum information science schemes.
