• Abstract: A measurement can extract work from an entangled, e.g., two-mode system. Here, we inquire the extracted work when no intellectual creature, like an ancilla/daemon, is present. When the monitoring is carried out by the environmental modes, that is when no measurement-apparatus is present, the measurement-basis becomes the coherent state. This implies a Gaussian measurement with a fixed strength $\lambda=1$. For two-mode Gaussian states, extracted work is already independent from the measurement outcome. After the strength is also fixed, this makes nature assign a particular amount of work to a given entanglement degree. Extracted work becomes the entanglement-degree times the entire thermal energy at low temperatures -- e.g., room temperature for optical modes. Environment, nature itself, converts entanglement to an ordered, macroscopic, directional~(kinetic) energy from a disordered, microscopic, randomized thermal energy. And the converted amount is solely determined by the entanglement.

• Detection of entanglement by harnessing extracted work in an opto-magno-mechanics [0.0]
  We address a bipartite entanglement via extracted work in a cavity magnomechanical system inside an yttrium iron garnet sphere. The extracted work was obtained through a device similar to the Szil'ard engine. We employ logarithmic negativity to measure the amount of entanglement between photon and magnon modes in steady and dynamical states.

  A local measurement extracts work as a backaction in a system of two entangled cavities. We show that this makes nature assign a textitfixed amount of work to a particular entanglement degree. We also show that such a change in the character of the motion introduces curvature in spacetime according to general relativity.

  We experimentally demonstrate how to generate a state in condensed matter at moderate cryogenic temperatures. This state is then used to efficiently remove microwave photons from a cavity. Such an "anti-maser" device could be extremely beneficial for applications that would normally require cooling to millikelvin temperatures.

• Daemonic ergotropy in continuously-monitored open quantum batteries [0.0]
  daemonic ergotropy is introduced to properly describe and quantify this work extraction enhancement in the quantum regime. We show that the corresponding daemonic ergotropy takes values between the ergotropy and the energy of the corresponding unconditional state. The upper bound is achieved by assuming an initial pure state and a perfectly efficient projective measurement on the environment.

• Classicality of the heat produced by quantum measurements [0.0]
  We model the measurement process for an arbitrary discrete observable as a measurement scheme. The work can be interpreted as the change in internal energy of the compound system due to the unitary coupling. We argue that the apparatus serves as a stable record for the measurement outcomes only if the pointer observable commutes with the Hamiltonian.

  We develop an alternative theoretical framework for the thermodynamic analysis of two-level systems. We observe the appearance of a new term of work, which represents the energy cost of rotating the Bloch vector in presence of the external field that defines the local Hamiltonian. In order to illustrate our findings we study, from both perspectives, matter-radiation interaction processes for two different systems.
