Philip Walther, colleagues and collaborators publish their latest findings in Quantum

Physicists at the University of Vienna, in collaboration with the Federal University of Santa Catarina in Brazil, have empowered Maxwell’s Demon using correlations to provide the Demon with extra information to extract work more efficiently.

The scientists used tools from quantum photonics to create a Maxwell’s Demon which sorts hot correlated photons from cold ones. Due to these correlations when the Demon measures one photon it also gains information about unmeasured photons. It can convert this information into additional work. The results of the experiment were published in the current issue of Quantum.
