Researchers from the Moscow Institute of Physics and Technology, ETH Zurich, and Argonne National Laboratory, U.S, have described an extended quantum Maxwell's demon, a device locally violating the second law of thermodynamics in a system located one to five meters away from the demon. The device could find applications in quantum computers and microscopic refrigerators that cool down tiny objects with pinpoint accuracy. The research was published Dec. 4 in Physical Review B.
