The quantum three-wave interaction, the lowest order nonlinear interaction inplasma physics, describes energy-momentum transfer between three resonant wavesin the quantum regime. We describe how it may also act as afinite-degree-of-freedom approximation to the classical three-wave interactionin certain circumstances. By promoting the field variables to operators, wequantize the classical system, show that the quantum system has more freeparameters than the classical system, and explain how these parameters may beselected to optimize either initial or long-term correspondence. We thennumerically compare the long-time quantum/classical correspondence far from thefixed point dynamics. We discuss the Poincare recurrence of the system and themitigation of quantum scrambling.
