Semiconductor Nanostructures for Quantum Computation

Abstract

Quantum computation is a new computational paradigm that has challenged the research community to find ways to control individual quantum elements. Perhaps the progress made in this direction will provide a foundation for construction of practical quantum computers. Even if not, manipulation and control of the smallest elements of information possible, these qubits, will lead to important applications in electronics, optics, and magnetics. Full control in the manipulation of qubits can only take place when the properties of materials and devices are engineered on the atomic scale, whether it is through quantum dots, or through the careful positioning of individual phosphorus atoms in silicon.
