Author(s): Akash Chohan*

Quantum computing operates using qubits, the basic units of quantum information, which enable quantum algorithms to solve complex problems that classical computers cannot efficiently handle. This review provides a comparative analysis of several promising qu bit technologies, including su perconducting qubits, topological q ubits, spin qubits, photonic qubits, ion trap qubits, and Nitrogen Nitrogen-Vacancy (NV) centers in di amonds. We discuss the operational principles, key researchers and institutions in each field, current advancements, challenges, and future directions for these te chnologies. This paper aims to present a thorough overview of the different approaches in qubit technologies and their potential impacts on quantum com puting’s future landscape.
