OPQUT IMPULZ IM-2023-79

Title: Operational Quantum Thermodynamics
Duration: 15/09/2024 - 14/09/2029
Principal Investigator: Dr. M. Hamed Mohammady
Budget: 749 056 €

Project Mission: This is a proposal for the applicant to build a research group in the Institute of Physics of the Slovak Academy of Sciences, in order to establish a resource theoretic framework for operational quantum thermodynamics. To date, the resource theory of quantum thermodynamics has been founded on the operationally unjustified assumption of unitarity of the global dynamics, and has only addressed the thermodynamic costs of transforming one quantum state to another state. In this project, the applicant will provide the resource theory of quantum thermodynamics with a fully operational foundation that does not rely on unitarity, and will investigate the thermodynamic costs of other tasks in operational quantum physics such as: performing quantum measurements, implementing incompatible quantum processes, and the higher-order task of transforming one quantum process to another quantum process.
