Wave-particle duality is one of the most notable and counterintuitive features of quantum mechanics, illustrating that two incompatible observables cannot be measured simultaneously with arbitrary precision. In this work, we experimentally demonstrate the equivalence of wave-particle duality and entropic uncertainty relations using orbital angular momentum (OAM) states of light. Our experiment uses an innovative and reconfigurable platform composed of few-mode optical fibers and photonic lanterns, showcasing the versatility of this technology for quantum information processing. Our results provide fundamental insights into the complementarity principle from an informational perspective, with implications for the broader field of quantum technologies.

This study of the article proposes an interdisciplinary approach, integrating quantum mechanics and structuralism to elucidate the complex dynamics of signification. By paralleling the ambiguous nature of subatomic particles with the linguistic system, the study examines the arbitrary relationship between sign, signifier, and signified through quantum principles. Key concepts from quantum mechanics, such as wave-particle duality, superposition, entanglement, and observer effect, are applied to Saussure's theory of signs, revealing intriguing analogies between the two domains.

Article Synopsis
- High-resolution phase-contrast images from electron microscopes capture electron interactions, requiring a nuanced understanding of wave behavior and phase coherence over time.
- The study links the concepts of phase decoherence, energy uncertainty, and coherence length to explain how interactions between electrons and materials affect imaging quality.
- The findings reveal that when the self-coherence length falls below the crystal unit cell size, it disrupts coherent illumination, potentially influencing broader understanding of interactions in quantum mechanics.

Quantum interference is a natural consequence of wave-particle duality in quantum mechanics, and is widely observed at the atomic scale. One interesting manifestation of quantum interference is coherent population trapping (CPT), first proposed in three-level driven atomic systems and observed in quantum optical experiments. Here, we demonstrate CPT in a gate-defined semiconductor double quantum dot (DQD), with some unique twists as compared to the atomic systems.

However, the explanation for the photonic spin Hall effect (PSHE) primarily relies on the wave nature of light as dictated by Maxwell's Equations. There is a lack of exploration into the particle nature of light in this regard.
