    Constant-temperature dynamics in the Wigner representation of quantum mechanics. 

    Megnidio-Tchoukouegno, Mireille Merlise. (2011)
    This dissertation deals with theory and algorithms for computer simulations of classical and quantum systems in the canonical ensemble. First, the approach of Nos e-Hoover and its generalization, known as the Nos e- Hoover ...

    First principles quantum mechanical studies of iridium : a focus on bulk and surface properties. 

    Grussendorff, Sharon Joy. (2003)
    Recent high-pressure experiments on iridium show a transition to a 14 atomic layer superlattice structure. Since iridium has a high bulk modulus, it is used in many high-pressure applications, for instance as a gasket for ...

    Quantum dynamics in the partial Wigner picture. 

    Beck, Geoffrey Martin. (2013)
    The Wigner formalism can be used to provide a representation of quantum dynamics in a classical-like phase space. However, there are many cases, such as when dealing with spin systems in a dissipative environment, in ...

    On non-Hermitian quantum mechanics. 

    Peacock, Jared L. (2013)
    The purpose of this dissertation is to review the salient features of non-Hermitian quantum mechanics. An introduction to Hermitian quantum mechanics is included to make this review as accessible as possible. Attempts ...

    The implementation of polarisation encoded quantum key distribution in fibre. 

    Pillay, Sharmini. (2012)
    Quantum Key Distribution (QKD) employs the laws of quantum mechanics for the purpose of cryptography. Two parties, commonly called Alice and Bob, are able to share a random key which is used to encrypt a message. Any ...

    Optimizing quantum communication through hybrid technology. 

    Mirza, Abdul R. (2012)
    Quantum Key Distribution (QKD) is a symmetric key sharing protocol. The theoretical process exploits the principles of quantum physics to underpin a physical security against any form of eavesdropping. QKD not only ensures ...

    Exactly solvable models for qubits coupled to spin environments : decoherence and entanglement. 

    Hamdouni, Yamen. (2008)
    During the last decade the field of quantum information has seen considerable progress both theoretically and experimentally. The building block of this theory is the so-called qubit, the quantum counterpart of the ...

    Monitoring the states of single quantum systems. 

    Garapo, Kevin. (2012)
    Continuous weak measurement provide a convenient way to gather information about a quantum system without the need to prepare huge ensembles of identical systems as required by standard quantum measurement theory. Even ...

    Security and entanglement in differential-phase-shift quantum key distribution. 

    Marais, Adriana. (2009)
    Quantum key distribution (QKD) aims at the creation of a secret key in the two locations of partners, traditionally Alice and Bob, wishing to communicate in private. A generic QKD protocol utilises a quantum channel and ...

    Quantum dynamics in classical constant-temperature baths. 

    Dlamini, Nkosinathi B. (2012)
    In this dissertation the formulation of various integration algorithms is studied, with a view to simulate quantum-classical systems in contact with a thermal bath. In particular focus is given to the constant temperature ...
