Demon in the details of quantum thermodynamics

Researchers have discovered that using information to extract work on a quantum scale is possible, but it comes with a catch: some information may be lost in the process. Quantum backaction allows researchers to measure particles without fully collapsing their superposition states, resulting in negative information.
