Solvable Models on Noncommutative Spaces with Minimal Length Uncertainty Relations
… arguments involving standard quantum mechanical uncertainty relations suggest that at length scales close to the Planck length, strong gravity effects limit the spatial as well as temporal resolution smaller than fundamental length scale, leading to space-space as well as spacetime uncertainties. …

Quantum optical state comparison amplification
… them is their intrinsic noise. This results in uncertainty relations restricting our ability to measure conjugate variables with absolute precision simultaneously. In the context of amplification, this noise forbids an unknown quantum signal to be amplified perfectly in a deterministic manner. …

Novel Derivations of the Metric from the Newtonian Potential and of the Relativistic Quantum Equation
… equation. The operators are derived, and the uncertainty relations are found. Solutions are analyzed for the flatspace metric. The relativistic harmonic oscillator and 1/r potentials are also presented. The 1/r potential is useful for studying the motion of a particle orbiting a hydrogen atom …

A Study of Modifications to Quantum Mechanics
… ones in which the canonical commutation relations between position and momentum are deformed and ones in which the space of states used are vector spaces over Galois fields instead of complex Hilbert spaces. The particular deformation of the canonical commutation relations used leads to a …

On the nature and decay of quantum relative entropy
… and coherence, and in the form of entropic uncertainty relations between incompatible measurements. The theme of this dissertation is the quantum nature of entropy, and how exposure to a noisy environment limits and degrades non-classical features. An especially useful and general form of …

Uncertainty Estimation on Natural Language Processing
… an NLP model's predictions, which is our focus-uncertainty estimation on NLP. Though many works have researched uncertainty estimation or NLP, the combination of these two domains is rare. This is because most NLP research emphasizes model prediction performance but tends to overlook the …
