Abstract: Quantum key distribution (QKD) and quantum secret sharing play a pivotal role in securing con dential information. QKD allows legitimate parties to create a cryptographic key which they can use to communicate privately without being intercepted by a malicious eavesdropper. QKD exploits the laws of quantum mechanics such as the Heisenberg uncertainty principle, the no cloning theorem and the principle of entanglement to detect any eavesdropper who tries to gain the knowledge of the ...
Abstract: This work is primarily focused on probing quantum gravity through astrophysical observations based on the theoretical framework of the Nexus Paradigm of quantum gravity. The Nexus Paradigm is a theoretical framework that is still in development and offers a different approach to the problem of quantum theory of gravity. In this framework gravity, Dark Energy (DE) and Dark Matter (DM) are seen as different manifestations of the quantum gravity. Astrophysical observations offer a...
Abstract The study focuses on the potential of naturally occurring dyes as photosensitizers in dye-sensitized solar cells (DSSCs). DSSCs are a type of solar cell that uses chemicals called photosensitizers to absorb energy from visible light and produce excited electrons. In 1991, Grätzel and his co-workers developed DSSCs, which have gained attention in recent years. However, the ruthenium-based compounds used as photosensitizers are expensive, and research suggests that organic dyes ...
Naturally occurring radionuclide materials are usually absorbed by plants through their root systems as nutrients, which in turn pose a radiation risk to humans when they consume the plants as food. This study evaluated the radionuclide risks from naturally occurring radionuclides in samples of commonly consumed vegetables in Owerri. Gamma ray spectroscopy was used to analyze and profile the 226Ra, 232Th and 40K levels in the vegetable samples of African basil, water leaf, uziza leaf and bitt...
