The 20th century witnessed the birth and rapid development of quantum mechanics. As it matured, it deeply revamped other branches of physics, e.g., electrodynamics, solid state physics, and even cosmology. Recently, a new interest has awakened – how quantum mechanics can rewrite the rules of thermodynamics, a branch of physics primarily concerned with exchange of heat and work during transformations of a system. This fusion, termed quantum thermodynamics, aims to search for a “quantum advantage” in thermodynamics, in some sense akin to the quantum advantage intensely sought after in information science. Specifically, it is concerned with how purely quantum mechanical resources – superposition, entanglement, and measurement – can be utilized in a thermodynamic machine operating at the quantum level. We are exploring quantum thermodynamics using circuit quantum electrodynamics because it offers an excellent platform for control and manipulation of quantum systems.
