Semiconductor Physics and Systems

Semiconductors doped with impurities are a new and fascinating candidate for quantum computing. The introduction of impurities with one additional electron into the semiconductor's structure alters its electronic characteristics to create a set of bound hydrogen-like orbital wave functions of the extra electron. We can manipulate these orbitals using lasers, electric and magnetic fields to get the radii of adjacent orbitals to overlap. This interaction can be harnessed for quantum computing applications, notably entanglement.
