    "abstract": "We propose a quantum analog of the internal combustion engine used in most\ncars. Specifically, we study how to implement the Otto-type quantum heat engine\n(QHE) with the assistance of a Maxwell\u0027s demon. Three steps are required:\nthermalization, quantum measurement, and quantum feedback controlled by the\nMaxwell demon. We derive the positive-work condition of this composite QHE. Our\nQHE can be constructed using superconducting quantum circuits. We explicitly\ndemonstrate the essential role of the demon in this macroscopic QHE.",
