Contribution

It demonstrates how quantum theory imposes no-go results on cloning and masking of thermodynamic quantities, revealing new constraints in quantum thermodynamics.

Findings

Quantum theory prohibits cloning of thermodynamic quantities.

Quantum masking of work and energy is impossible.

Abstract

Thermodynamics is one of the fascinating branches of traditional physics to certify the occurrence of many natural processes. On the other hand, quantum theory is the most acceptable description of the microscopic world. In the present work, we have studied how the structure of quantum theory prohibits cloning or masking of several thermodynamic quantities, viz., work and energy stored in a quantum state. Our results have important consequences in quantum partial cloning, quantum masking and on the action of quantum channels.
