" Maxwells demon is a hypothetical being of intelligence with molecular

order of size imagined to illustrate limitation of the second law of

thermodynamics. The Szilard engine (SZE), a physical realization

of Maxwells demon,is a machinery which extracts useful work from

information entropy. We have investigated its fully quantum mechanical

description and found the amount of extractable work is given by the

so-called relative entropy. We also discuss manifestation of quantum

statistical nature of identical particles, i.e. bosons and fermions, in a

many-particle quantum SZE. In this talk you will enjoy various aspects

of information in Physics."
