We demonstrate that transient four-wave mixing with time-resolved detection of the coherent nonlinear signal allows unambiguous experimental distinction between quantum beats and beats due to interfering polarizations of independent quantum-mechanical systems. The experimental demonstration is performed employing especially designed semicondutor quantum-well structures.
