Summary
This study introduces a novel quantum framework integrating plausibility, credibility, and possibility to better model uncertainty. This enhanced approach improves quantum system analysis and decision-making in complex information environments.
Area of Science:
- Quantum Information Science
- Epistemology
- Uncertainty Quantification
Background:
- Classical probability theory struggles with non-Kolmogorovian phenomena in quantum systems.
- Partial, noisy, or ambiguous information challenges traditional decision-making models.
- Existing quantum frameworks like QBism have limitations in capturing diverse uncertainty measures.
Purpose of the Study:
- To propose a novel quantum-informed epistemic framework extending classical probability.
- To integrate plausibility, credibility, and possibility as distinct uncertainty measures.
- To develop a robust model for quantum systems and decision-making under ambiguous information.
Main Methods:
- Developed an enriched quadruple (P, Pl, Cr, Ps) for uncertainty characterization.
- Generalized the Born rule using multi-valued logic and linked POVMs with estimators.
- Constructed a hybrid classical-quantum inference engine for vectorial aggregation of quadruples.
Main Results:
- The framework successfully models non-Kolmogorovian quantum phenomena like entanglement and contextuality.
- The hybrid inference engine enhances robustness and semantic expressivity beyond classical probability.
- Demonstrated superior performance in accuracy, noise resilience, interpretability, and decision stability across applications.
Conclusions:
- The proposed quantum-informed epistemic framework offers a powerful new paradigm for uncertainty.
- It outperforms existing methods in quantum cybersecurity, quantum AI, and financial computing.
- Lays the foundation for epistemic quantum computing beyond traditional probabilistic models.

An experiment often consists of more than a single step. In this case, measurements at each step give rise to uncertainty. Because the measurements occur in successive steps, the uncertainty in one step necessarily contributes to that in the subsequent step. As we perform statistical analysis on these types of experiments, we must learn to account for the propagation of uncertainty from one step to the next. The propagation of uncertainty depends on the type of arithmetic operation performed on...

The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined that there is a fundamental limit to how accurately one can measure both a particle’s position and its momentum simultaneously. The more accurate the measurement of the momentum of a particle is known, the less accurate the position at that time is known and vice versa. This is what is now called the Heisenberg uncertainty principle. He...

Continuous probability distributions are used to model random variables that can take on any real value within a specified range. These variables do not take on isolated or countable values but rather exist on a continuum. For example, the height of an individual can be measured with increasing precision—such as 163.5 or 165.25 centimeters—demonstrating that height is a continuous random variable.The behavior of such variables is described using a probability density function (PDF),...

00:59Uncertainty: Overview
1.6K
In analytical chemistry, we often perform repetitive measurements to detect and minimize inaccuracies caused by both determinate and indeterminate errors. Despite the cares we take, the presence of random errors means that repeated measurements almost never have exactly the same magnitude. The collective difference between these measurements - observed values - and the estimated or expected value is called uncertainty. Uncertainty is conventionally written after the estimated or expected value.

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.
