Abstract: Quantum science underpins many of the most significant advances in modern physics, chemistry, and information technology. Quantum physics provides the fundamental laws governing matter and energy at microscopic scales, quantum chemistry applies these principles to explain molecular structure, bonding, and reactivity, and quantum computing seeks to exploit quantum phenomena such as superposition and entanglement to enable new computational paradigms. Despite their long-standing theoretical foundations and experimental successes, all three domains remain surrounded by persistent misconceptions, often amplified by abstract formalisms, popular science narratives, and rapid technological developments. This contemporary review critically examines the established facts and common myths associated with quantum physics, quantum chemistry, and quantum computing. Emphasis is placed on experimentally verified principles, computational feasibility, and realistic assessments of current capabilities. Recent advances reported between 2020 and 2025 are reviewed to highlight genuine progress in areas such as quantum simulations, molecular modeling, and noisy intermediate-scale quantum (NISQ) devices, while also addressing their practical limitations. By distinguishing validated achievements from speculative claims, this review provides a balanced, evidence-based perspective on modern quantum science. The article aims to clarify enduring misconceptions, promote conceptual clarity across disciplines, and outline realistic future directions for research and applications in quantum technologies.

Abstract: This theoretical work give a comprehensive properties of a Schiff base compound that is formed when amines and ketone or aldehyde are combined. The investigated Schiff base compounds were designed by combining primary amines with ketones or aldehydes. The spectroscopic characteristics, molecular structure, electrostatic potential maps, and other molecular properties of these compounds had been computed at the B3LYP Functional with a 6-311G(d,p) basic set. The optimization and transition states of the molecules were analyzed by applying the B3LYP Functional with a 6-31G(d,p) basic set, based on density functional theory (DFT) and time-dependent density functional theory (TD-DFT) for ground-state and excited-state calculations, respectively. We had also determine the band length and band angles of the designed molecules. Several computational software packages was used to study the spectroscopic, electronics, and molecular characteristics of explore Schiff base compounds. The molecules were designed in GaussView5 and optimized in Gaussian 09. PyMolyze and Origin6.0 software were used to perform the density of state (DOS) analysis & to draw the absorption spectra of probe molecules. TDM analysis were conducted to determine the charge distribution in the investigated molecules using Multiwfn3.7 and VMD1.9.1 software. Correlation statistical models were employed to interpret the statistical data. The docking results of the designed molecules were compared with antibacterial standards, and we expect these results to show greater efficiency than the reference molecules. Additionally, the antitumor and antibacterial characteristics of a designed molecule were compared with those of the reference molecules.
