Entanglement is an important phenomenon that enables quantum information processing
algorithms and quantum communications protocols. Although entangled quantum states are …

A common model of quantum computing is the gate model with binary basis states. Here, we
consider the gate model of quantum computing with a non-binary radix resulting in more …

A recently developed four-port coupler used in optical signal processing applications is
shown to be equivalent to a Chrestenson operator, or gate, in radix-4 quantum information …

Quantum information processing and communication techniques rely heavily upon
entangled quantum states, and this dependence motivates the development of methods and …

An architecture for a quantum photonic true random number generator (TRNG) that takes
advantage of higher-radix encoding schemes is presented. The TRNG is based upon two …

The models and rules of quantum computation and quantum information processing (QIP)
differ greatly from those that govern classical computation, and these differences have …

The aim of this work is to prove that it is possible to realise an optical system which produces
as output a light intensity that can be expressed in the same mathematical form of the spin …

BACKGROUND Certain computational problems, such as the factoring of large numbers,
cannot easily be solved using conventional computers due to the time required to complete …

ACKNOWLEDGMENTS I am grateful for the many people in my life who made the
completion of this dissertation possible. First, I would like to thank Dr. Mitch Thornton for …
