Anomalies of Wave-Particle Duality due to Internal-Translational Entanglement
Authors: Michal Kolar, Tomas Opatrny, Nir Bar-Gill, Gershon Kurizki
Comments: 4 pages, 3 figures

We predict that if internal and momentum states of the interfering object are correlated (entangled), then by measuring its internal state we may infer both path (corpuscular) and phase (wavelike) information with much higher precision than for objects lacking such entanglement, thereby circumventing the complementarity constraints. This anomaly provides new insights into wave-particle duality.

The concept of wave-particle duality has been a fundamental principle in quantum mechanics, describing the behavior of particles at the microscopic level. However, this principle has been challenged by various anomalies, such as the one proposed by Kolar et al. in their paper "Anomalies of Wave-Particle Duality due to Internal-Translational Entanglement".

Their work suggests that the traditional understanding of wave-particle duality can be circumvented by the presence of internal-translational entanglement. This means that if the internal and momentum states of an interfering object are correlated, then by measuring the internal state, one can obtain both path and phase information with higher precision than for objects without such entanglement.

This anomaly challenges the traditional understanding of wave-particle duality, which states that it is impossible to simultaneously know both the path and phase of a particle. Kolar et al.'s work suggests that this limitation can be overcome by considering the entanglement between the internal and momentum states of the particle.

This anomaly provides new insights into the nature of wave-particle duality and highlights the importance of entanglement in understanding the behavior of particles at the quantum level. It also has potential implications for future quantum technologies, where the precise control of entanglement could lead to better precision and accuracy in measurements and experiments.

In conclusion, the work presented by Kolar et al. sheds light on the anomalies of wave-particle duality and suggests that the traditional understanding of this principle may need to be revised in light of the role of entanglement. Further research in this area could lead to a deeper understanding of the fundamental principles of quantum mechanics and their applications in various fields.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
According to recent podcast between Jacob Barandes and Sean Carroll, Barandes claims that putting a sensitive qubit near one of the slits of a double slit interference experiment is sufficient to break the interference pattern. Here are his words from the official transcript: Is that true? Caveats I see: The qubit is a quantum object, so if the particle was in a superposition of up and down, the qubit can be in a superposition too. Measuring the qubit in an orthogonal direction might...
