Summary
Quantum irrealism, the violation of realism by quantum mechanics, is affected by Lorentz boosts. Physical realism is not absolute and depends on the observer's inertial frame.
Area of Science:
- Relativistic quantum information theory
- Foundations of quantum mechanics
- Quantum entanglement
Background:
- Spin-momentum entanglement is not Lorentz covariant, prompting research into relativistic quantum information.
- Quantum mechanics challenges classical notions of realism.
Purpose of the Study:
- To investigate whether Lorentz boosts impact quantum irrealism.
- To explore the relationship between relativistic effects and the concept of realism in quantum systems.
Main Methods:
- A theoretical model of a relativistic particle in a Mach-Zehnder interferometer was used.
- Quantum irrealism was assessed from two different inertial frames in relative motion.
Main Results:
- Lorentz boosts were found to affect quantum irrealism.
- The study provides evidence that quantum irrealism is frame-dependent.
Conclusions:
- The notion of physical realism is not absolute.
- Relativistic effects, specifically Lorentz boosts, influence the manifestation of quantum irrealism.

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.

In 1905, Albert Einstein published his special theory of relativity. According to this theory, no matter in the universe can attain a speed greater than the speed of light in a vacuum, which thus serves as the speed limit of the universe.
This has been verified in many experiments. However, space and time are no longer absolute. Two observers moving relative to one another do not agree on the length of objects or the passage of time. The mechanics of objects based on Newton's laws of...

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...

The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

According to Albert Einstein (1897-1955), free-falling and feeling weightless are intrinsically linked. If a person were in free-fall under gravity, for example, diving towards the Earth from an airplane, they would feel completely weightless. Similarly, a person descending in a lift may feel partially weightless. Broadly speaking, it is assumed that an object in a uniform gravitational field and an object undergoing constant acceleration in the absence of gravity are under the same...
