  1. 1. Time-dependent light-matter coupling and quantum dynamics

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Daniel Elgbro; [2023]
    Keywords : light-matter interaction; Rabi oscillations; quantum dynamics; optical cavity; qubit; coupled qubit; coupling strength; time-dependent coupling; dynamical qubits; entanglement; concurrence; qubit state manipulation; Jaynes-Cummings; Tavis-Cummings; Physics and Astronomy;

    Abstract : In this thesis, two quantum dynamical system’s of one and two qubits coupled to a field mode confined in an optical cavity have been studied. Within the Jaynes- and Tavis- Cummings model, the dynamics of the corresponding light-matter interaction was defined in terms of the system’s coupling constants. READ MORE

  3. 2. Quantum statistics of a three-level maser

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

  4. 3. Laser cooling, state initialization and laser manipulation of a trapped ion

    University essay from Stockholms universitet/Fysikum

    Author : Julius Andersson; [2021]
    Keywords : Ion trap; Quantum computer;

    Abstract : One way of realizing a quantum computer is to use an ion trap. The research group Trapped Ion Quantum Technologies at Stockholm university were operating an ion trap with strontium ions. To increase the coherence time they installed a magnetic field shielding. Therefore the experimental setup had to be partially rebuilt. READ MORE
