  This paper covers some new results from the theory of time optimal quantum
control, with particular application to relativistic particles including
Majorana fermions. We give a brief review of the state of affairs regarding
experimental results, and a concise overview of the methodology of time optimal
control and unitary transformation. This technique is then applied to the
Majorana particle and used to derive four dimensional conservation laws. We
then discuss the nature of time transformation in these systems and some simple
scattering problems.
