Our study compares the Wigner and Husimi distributions for an anharmonic oscillator, focusing on entropy and mutual information analysis. The Wigner distribution typically exhibits lower entropy and preserves more information, consistent with theoretical uncertainty limits. In contrast, the Husimi distribution experiences greater information loss, making the Wigner distribution a more accurate representation of the system’s information content.

摘要

Our study compares the Wigner and Husimi distributions for an anharmonic oscillator, focusing on entropy and mutual information analysis. The Wigner distribution typically exhibits lower entropy and preserves more information, consistent with theoretical uncertainty limits. In contrast, the Husimi distribution experiences greater information loss, making the Wigner distribution a more accurate representation of the system’s information content.
