CURRENT RESEARCH IN QUANTUM COMPUTING: Two current research and development areas fuel this 15 year old field: 1) chip technologists creating transistors of smaller and smaller sizes and 2) atomic physicists manipulating individual atoms with an increasing level of sophistication. The ultimate goal of each is a computer with transistors of atomic size, which will manipulate qubits to produce quantum-type calculations. My research interests are in the area of theoretical Quantum Computing, i.e. the creation of algorithms to solve practical problems on a quantum computer such as IBM Q.
AND DEVELOPMENT April 1997 - present R&D contract with I-Image Medical Technologies Inc., Montreal. Design and development of a pattern recognition program which measures and analyses eye blood vessels in the assessment of an ophthalmic patient before and after medical or surgical interventions. This program, developed in Visual C++, lead to an approved patent.
