2 Jan 2023 | | 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. | | Source: | arXiv, 2301.00574 | | Services: | Forum | Review | PDF | Favorites | |
