Query: Theory of Coherent Optical Control of Exciton Spin Dynamics in a
  Semiconductor Quantum Dot   We use the spin-polarized excitons in a single quantum dot to design optical
controls for basic operations in quantum computing. We examine the ultrafast
nonlinear optical processes required and use the coherent nonlinear optical
responses to deduce if such processes are physically reasonable. The importance
and construction of an entangled state of polarized exciton states in a single
quantum dot is explained. We put our proposal in perspective with respect to a
number of theoretical suggestions of utilizing the semiconductor quantum dots.
