Title: Heat as a witness of quantum properties
Authors: A. de Oliveira Junior, Jonatan Bohr Brask, Patryk Lipka-Bartosik,
Abstract summary: We present a new approach for witnessing quantum resources, including entanglement and coherence, based on heat generation. Inspired by the concept of Maxwell's demon, we analyze the heat exchange between a quantum system and a thermal environment. We find that quantum states can reveal their non-classical signatures via energy exchange with a thermal environment.

Abstract: We present a new approach for witnessing quantum resources, including entanglement and coherence, based on heat generation. Inspired by the concept of Maxwell's demon, we analyze the heat exchange between a quantum system and a thermal environment assisted by a quantum memory. By exploring the fundamental limitations of heat transfer in this scenario, we find that quantum states can reveal their non-classical signatures via energy exchange with a thermal environment. This approach offers a promising alternative to complex, system-specific measurements, as it relies solely on fixed energy measurements. To demonstrate the effectiveness of our method, we apply it to the detection of entanglement in isotropic states and coherence in a two-spin system interacting with a single-mode electromagnetic field.
