"move excitons in much smaller packages than previously possible... laser create excitons cloud at pyramid's base, bouncing electrons out of valence band into conduction band... landscape governed by how far apart semiconductor's valence and conduction bands are: semiconductor's band gap shrinks where semiconductor stretched... excitons migrate to lowest energy state and rise to pyramid's peak... combination of optics and excitonics for fast efficient exciton devices potentially including room temperature quantum computers"
