Seyed Navid Elyasi - Experimental Simulation of Open Quantum Batteries: Daemonic Work Extraction in Action

Abstract:
The possibility of extracting more work from a physical system through information gained from measurements has been a central topic in thermodynamics since the proposal of Maxwell's demon. In this work, we address this concept using the framework of an open quantum battery interacting with an environment under continuous measurement. By modeling the system with a continuously monitored collisional model, we construct a quantum circuit that captures its dynamics, including the conditional feedback unitary evolution required to enhance work extraction. Using IBM quantum computers, we experimentally simulate this protocol, showing that the extracted daemonic work closely approaches the theoretical upper bound, quantified by the daemonic ergotropy. Furthermore, we demonstrate how modeling noise within the circuit enables optimization of the feedback operation, leading to improved work extraction performance.
