Physicists Hooman Moradpour and S. Jalalzadeh propose that a fundamental minimal length in quantum mechanics inherently introduces non-Hermiticity, challenging traditional quantum operator properties and suggesting complex eigenvalues may arise naturally from spacetime constraints. The study bridges canonical momentum measurements with generalized momentum operators modified by minimal length effects, revealing discrepancies that could redefine quantum measurement frameworks in high-energy or gravitational regimes. Complex numbers in quantum mechanics gain new justification as a direct consequence of minimal length, implying these mathematical tools may reflect deeper physical reality rather than mere calculational convenience. A novel method for generating entangled states with complex quantum numbers emerges from minimal length constraints, offering potential advancements in quantum information protocols and tests of non-locality. The findings suggest quantum gravity theories incorporating minimal length could enrich understanding of non-locality, providing testable connections between quantum foundations and spacetime structure.

Jalalzadeh View a PDF of the paper titled Minimal length: a source of non-Hermiticity and non-locality in quantum mechanics, by H. Moradpour and 1 other authors View PDF HTML (experimental) Abstract:First, the study tries to shed light on the relationship between purely quantum mechanical momentum measurements (canonical momentum space) and measurements of the generalized momentum operator, including minimal length effects. Additionally, the existence of complex numbers in quantum mechanics seems justifiable as a consequence of minimal length. Finally, a novel method for generating quantum entangled states with complex quantum numbers inspired by the minimal length is also reported. Therefore, theories including a minimal length, like some quantum scenarios of gravity, seem to be able to enrich the current understanding of non-locality.
