| Outline of Final Research Achievements |
Project members were able to meet and fulfill all major goals of the grant. To begin, project members were able to derive an extension and reformulation of the Wigner function. Project members were then able to verify that the updated formalism elucidates various quantum properties, such as entanglement, through the visualization of specific "slices" of the various representations of the aforementioned functions. Lastly, project members were successful in developing two visualization packages for said Wigner functions based upon the updated formalism; the first being done in Python and integrated into IBM's QISKit software package; the second being done in Swift for analysis of chemical systems.

| Academic Significance and Societal Importance of the Research Achievements |
Our work generated two software packages; a half-dozen papers; advanced the visualization of quantum correlations in atomic, molecular, and chemical systems; and was instrumental in verifying the quantumness of a 20-qubit Schrodinger cat state (see Song et al., Science 365, 574-577 (2019)).
