1. A logic gate adapted to implement logical expressions, the logic gate comprising: at least one input adapted to receive an input signal and at least one control signal, wherein at least one of the input signal and the control signal is a noise signal; at least one output adapted to produce an output signal; and a nonlinear updater that operates as a dynamically configurable element to produce a plurality of different logic gates as selected by the control signal based at least in part on the noise signal, the nonlinear updater electrically coupled to the input and electrically coupled to the output and configured to apply a nonlinear function to the input signal in response to the control signal to produce the output signal representing a logical expression being implemented by one of the plurality of different logic gates on the input signal.
