A ten-year disagreement over fundamental limits within fractional quantum mechanics has ended with a revised understanding of how precisely properties like position and momentum can be known simultaneously. Exact calculations using the Lévy wave packet now demonstrate an improved lower bound, one which scales almost linearly with the system’s defining parameter. These findings resolve inconsistencies plaguing previous approaches to quantifying this inherent quantum fuzziness.
