Summary
Quantum properties can be graded without being indeterminate. This study challenges the link between gradedness and indeterminacy, suggesting a new perspective on quantum ontology and properties.
Area of Science:
- Quantum mechanics
- Metaphysics
- Philosophy of science
Background:
- The graded view links quantum property gradedness to indeterminacy.
- This connection is influential in debates on quantum value indefiniteness.
Purpose of the Study:
- To challenge the inherent link between gradedness and indeterminacy in quantum properties.
- To present a graded quantum property that does not entail metaphysical indeterminacy.
- To offer a novel perspective on quantum ontology.
Main Methods:
- Investigated two graded approaches to location in quantum mechanics.
- Analyzed the concept of degreed instantiation of exact location.
- Examined the concept of degreed quantum location.
Main Results:
- Degreed instantiation of exact location was found to be indeterminate.
- Degreed quantum location was found *not* to be indeterminate.
- Demonstrated that gradedness and indeterminacy are not inherently linked.
Conclusions:
- Quantum properties can exhibit gradedness without metaphysical indeterminacy.
- Advocates for a graded view of quantum properties independent of indeterminacy.
- Suggests a potential paradigm shift in understanding quantum phenomena.

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...

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.

00:59Uncertainty: Overview
496
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.

It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one energy level to another but not transition smoothly or stay between these levels.

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

00:59Propagation of Uncertainty from Random Error
621
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...
