Quantum thermodynamics emerged from the need to study thermodynamic processes at the quantum realm, where effects such as entanglement and coherence play a crucial role. The field has seen rapid progress, extending far beyond its foundational roots. In the past decade, it has attracted the attention of experimentalists, who to put to test the thermodynamic laws reformulated for quantum mechanical processes, measure thermodynamic quantities such as work, heat, and entropy, verify fluctuation theorems, and even showcase quantum heat engines. Today, quantum thermodynamics is a cornerstone of quantum sciences, essential to the development of disruptive quantum technologies, from sensors to quantum computers.
