We formulate a theory of quantum feedback control of a single quantum particle in a harmonic potential. By continuously monitoring a combination of position and momentum we can feedback an appropriate force proportional to the measured signal to cool and confine the system. We derive a master equation which describes the feedback control in order to calculate the final temperature as a function of the feedback gain and measurement strength.
