Quantum thermodynamics, an emerging interdisciplinary field, bridges the gap between quantum mechanics and classical thermodynamics. This thesis delves into quantum thermodynamic phenomena and their real-world applications across multiple physical domains, placing a particular emphasis on quantum coherence. The work includes theoretical and experimental studies of thermoelectric and heat currents in hybrid superconducting structures, originating from coherent Cooper pair splitting and elastic cotunneling effects. Furthermore, the work examines entropy dynamics in correlated qubit systems, utilizing the mathematical formalism and results of quantum information theory. Finally, a global-distance quantum key distribution scheme is proposed. The solution leverages coherent optical states and is based on the quantum foundations of the Second Law of Thermodynamics. The work demonstrates the practical impact of the addressed thermodynamic phenomena, laying a foundation for future applications.
