Synthesis, characterization and application of luminescent quantum dots and microcrystalline phosphors a thesis presented to the academic faculty.
Quantum dot electron spins in quantum information processing we demonstrate a complete set of all-optical single-qubit operations on a single quantum dot spin: initialization, an arbitrary gate, and measurement first, initialization into a pure spin state (logical 0) is accomplished on a nanosecond timescale by optical pumping. 13 quantum dots in biological imaging applications 131 cytotoxicity of quantum dots 132 qd surface chemistry 133 multi-modal imaging 14 synthesis of colloidal quantum dots 141 the thermodynamics of nanocrystal nucleation and growth 1411 nucleation 1412 growth and size focussing 15 cuins 2 quantum dots 2.
A study of fluorescent nanoparticles: quantum dots and silica dots a thesis presented to the faculty of the graduate school of cornell university. Electrical control of quantum dot spin qubits abstract this thesis presents experiments exploring the interactions of electron spins with electric ﬁelds in devices of up to four quantum dots these experiments are particularly motivated by the prospect of using electric ﬁelds to control spin qubits. Natural sciences quantum computation promises exponential gains in the speeds for quantum simulation in essence any quantum mechanical system with two levels can be used for quantum com-putation to build a complete quantum computer, however, it needs to fulﬁll the requirements postulated by d divincenzo[4.
Quantum dot spins and microcavities for quantum information processing a dissertation submitted to the department of applied physics and the committee on graduate studies.
Quantum dot, essentially allowing for the synthesis of materials with arbitrary band gap energies figure 5: the electronic structure of quantum dots varies with the size of the dot the optical properties of quantum dots occur in part due to a unique effect known as quantum conﬁnement.
Optical spectroscopy of novel quantum dot structures romain toro abstract this thesis comprises works on novel quantum dot structures new ways of growing iii-v semiconductor quantum dots by integrating a ternary element or by growing on top of a silicon wafer are optically characterized, opening the way to.
