  This paper addresses the application of quantum entanglement and cryptography
for automation and control of dynamic systems. A dynamic system is a system
where the rates of changes of its state variables are not negligible. Quantum
entanglement is realized by the Spontaneous Parametric Down-conversion process.
Two entangled autonomous systems exhibit correlated behavior without any
classical communication in between them due to the quantum entanglement
phenomenon. Specifically, the behavior of a system, Bob, at a distance, is
correlated with a corresponding system, Alice. In an automation scenario, the
'Bob Robot' is entangled with the 'Alice Robot' in performing autonomous tasks
without any classical connection between them. Quantum cryptography is a
capability that allows guaranteed security. Such capabilities can be
implemented in control of autonomous mechanical systems where, for instance, an
'Alice Autonomous System' can control a 'Bob Autonomous System' for
applications of automation and robotics. The applications of quantum
technologies to mechanical systems, at a scale larger than the atomistic scale,
for control and automation, is a novel contribution of this paper. Notably, the
feedback control transfer function of an integrated classical dynamic system
and a quantum state is proposed.
