Abstract
This article proposes the concept of a "quadimel," defined as a quantum-dimensional element, as a conceptual framework for describing quantum processes in both physical and biological systems. In the physical context, semiconductor quantum-dimensional nanocrystals are considered as candidate quadimels, with quantum electron transport examined using a one-dimensional Schrödinger-equation framework, transmission through a rectangular quantum well, and associated resonance and conductivity relationships. The concept is subsequently extended to biological systems, particularly DNA and RNA nucleotides, based on their molecular structure and proposed electronic properties. The manuscript further explores the possible relationship between the physical degrees of freedom of a proposed quadimel and quantum-information concepts such as qubits. The proposed biological interpretation is preliminary and speculative and should be distinguished from established research on quantum-mechanical electronic states in DNA and from established quantum-confinement physics. The article identifies potential applications in quantum information, nanoelectronics, communications, and biological research while emphasizing the need for theoretical and experimental validation of the proposed biological model.
