East China Normal Team Proposes New Limit to Quantum Uncertainty
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.
The Lévy index is satisfied by exact, calculable solutions available in the literature. Quantum mechanics stands as a major physics achievement of the last century, confirmed by extensive experimental evidence. Nevertheless, modifications to quantum mechanics continue to be explored, driven by diverse physical and mathematical motivations. Konishi et al. connected string theory with observable quantum gravity effects using…
