  • [2011-07-02] Coherent control of collective atomic spins 

    Trail, Collin
    In this thesis I explore the use of collective spin angular momentum as a platform for quantum information processing. Such systems have several nice features that make them excellent choices for such protocols, especially ...
  • [2012-02-01] Continuous measurement quantum state tomography of atomic ensembles 

    Riofrío Almeida, Carlos
    Quantum state tomography is a fundamental tool in quantum information processing tasks. It allows us to estimate the state of a quantum system by measuring different observables on many identically prepared copies of the ...
  • [2010-09-03] Control of neutral atoms in optical lattices 

    Mischuck, Brian
    Neutral atoms are promising candidates to store and manipulate quantum information. In this thesis we examine several problems related to the control of neutral atoms for quantum computation and simulation. In the first ...
  • [2012-08-27] Fault-tolerance in two-dimensional topological systems 

    Anderson, Jonas
    This thesis is a collection of ideas with the general goal of building, at least in the abstract, a local fault-tolerant quantum computer. The connection between quantum information and topology has proven to be an ...
  • [2012-08-27] Quantum algorithms, symmetry, and Fourier analysis 

    Denney, Aaron Jafar
    I describe the role of symmetry in two quantum algorithms, with a focus on how that symmetry is made manifest by the Fourier transform. The Fourier transform can be considered in a wider context than the familiar one of ...
  • [2009-08-27] Quantum control of d-dimensional quantum systems with application to alkali atomic spins 

    Merkel, Seth
    In this dissertation I analyze Hamiltonian control of d-dimensional quantum systems as realized in alkali atomic spins. Alkali atoms provide an ideal platform for studies of quantum control due to the extreme precision ...
  • [2012-08-28] Quantum correlations, chaos and information 

    Madhok, Vaibhav
    Quantum chaos is the study of quantum systems whose classical description is chaotic. How does chaos manifest itself in the quantum world? In this spirit, we study the dynamical generation of entanglement as a signature ...
  • [2013-01-30] Split gate tunnel barriers in double top gated silicon metal-oxide-semiconductor nanostructures 

    Shirkhorshidian, Amir
    Quantum computers hold the promise of far exceeding the computational efficiency of classical computers in a variety of applications. An immense amount of interest has grown in spin-based silicon quantum computers where ...
