Quantum-Fuzzy Tensor Operators and Uncertainty-Band Bifurcation for Symmetry-Preserving State Discrimination
Abstract: A tensor-operator framework is developed for fuzzy conjunction, fuzzy disjunction, and symmetry-preserving state discrimination in multi-qubit quantum systems. In this formulation, fuzzy membership and non-membership degrees are represented through expectations of effect operators acting on density matrices, providing a natural bridge between fuzzy logic and quantum measurement theory. Conjunction and disjunction operations are extended to the quantum domain via tensorised channels, constructed using projective measurements and unitary transformations, enabling logical …

Exploring the Versatility of Fabry-Pérot Interferometers: From Spectroscopy to Sensing
Abstract: The fundamental concept of operation for the Fabry-Perot interferometer is interference. Coherent light bounces back and forth between two extremely reflecting mirrors as it travels through the interferometer. The device operates on a pattern of constructive and destructive interference that is produced by this. By carefully regulating the space between the mirrors, a resonant optical cavity is created. The Fabry-Perot interferometer (FPI) is one of the most important and versatile …
