Magic Trapping of a Three-Level System for Rydberg Quantum Computation
For over a decade, enormous e ort has been invested towards building a practical quantum computer. Such a machine promises to revolutionize scienti c computing, but there are many challenges to be overcome. The dominant problem for most proposals is decoherence: random and uncontrollable loss of …

Dinamica effettiva di sistemi quantistici driven chiusi e aperti
… and controlling quantum states in physical systems, called NISQ (Noisy Intermediate-Scale Quantum) computers. They constitute an important intermediate stage towards the demonstration of a large-scale quantum computer. Huge efforts have been and are being made in developing and engineering …

Progress towards cavity induced transparency
… a ground state with the excited state of a three-level system. In this thesis, I discuss the theory behind CIT and present the progress in our current experiment aimed at achieving CIT. In particular, I discuss the technical aspects of the experiment and give an overview of our experimental …

Experimental Test of Relativistic Time Dilation by Laser Spectroscopy of Fast Ions
… of previous experiments in this sector, the systematics of two Doppler-free techniques of collinear laser spectroscopy on a fast (v=0.064c) ion beam in a storage ring have been investigated. The first technique, Lambda-spectroscopy on a closed Lambda-type three-level system, suffered from a …

Psychiatric nursing described : an investigation of the role of the psychiatric nurse using Flanagan's critical incident technique
… incidents were inductively classified into a three-level system consisting of areas, categories and sub-categories constructed by the writer.<br/><br/>The classified critical incidents were used to describe the work of the psychiatric nurse and to examine the differences and similarities among …

A single-site resolution fermionic quantum-gas microscope
… cooling occurs when a coherent driving of a three-level system generates a spectrally narrow Fano-like resonance which can be set to favour red-sideband transitions over blue ones of the quantised vibrational levels in the optical lattice potential. During the cooling process, the …

Analysis Of Change Plans in Two Elementary School Districts For Teacher Evaluation Practices Following the New Illinois Performance Evaluation Reform Act of 2010 (PERA)
<p>This Change Plan paper is the second part of a three-part dissertation on the effect of new Illinois laws on teacher evaluation in suburban Chicago elementary districts. The Illinois Performance Evaluation Reform Act (PERA) of 2010, as modified by Senate Bill 7, was signed into law in June 2011 …

Gain and Noise Performance of Bi/Er Co-Doped Fibre Amplifiers
… from literatures. Two EDFA cases: simplified three-level system, and three-level system with Stark splitting and homogeneous broadening, are implemented as a practice to familiarize myself with modelling and implementation. In particular, I have used my experiment results of the EDFs and EDFAs …

Quantum technologies with superconducting artificial atoms
… In chapter 3, the implementation of a Lambda system in superconducting artificial atoms is discussed. Strategies for optimal design are investigated by means of optimal symmetry breaking and dynamical decoupling. Stimulated Raman Adiabatic Passage (STIRAP), an adiabatic population transfer …

Mobility and fluorescence of barium ions in xenon gas for the EXO experiment
… A model that treats the barium ion as a three level system is used to predict the total number of fluorescence counts and correct for optical pumping. A pressure broadening coefficient for Ba+ in xenon gas is extracted and limits for p-d and d-s nonradiative decay rates are extracted. …
