Abstract

The paper studies spin-orbit interaction (i.e. the effect the spin has on the particle's trajectory in a magnetic field) as a model of quantum computation. The two-level spin quantum system is examined using the stochastic mechanics formulation. The control of the entangled spin state is considered as a problem of control of the mean moment of a particles ensemble along a reference trajectory. It is shown that such a control can be succeeded by applying an open-loop control scheme.
