This thesis provides a basic thought of nonequilibrium thermodynamics for info processing. Ever because Maxwell's demon was once proposed within the 19th century, the connection among thermodynamics and data has attracted a lot cognizance since it issues the basis of the second one legislation of thermodynamics. From the fashionable standpoint, Maxwell's demon is formulated as a data processing gadget that plays size and suggestions on the point of thermal fluctuations. by means of unifying details concept, size idea, and the lately constructed thought of nonequilibrium statistical mechanics, the writer has developed a thought of "information thermodynamics," within which details contents and thermodynamic variables are handled on an equivalent footing. particularly, the utmost paintings that may be extracted by means of the demon and the minimal paintings that's wanted for size and knowledge erasure through the demon has been determined. also, generalizations of nonequilibrium family members similar to a Jarzynski equality for classical stochastic structures within the presence of suggestions keep an eye on were derived. one of many generalized equalities has lately been established experimentally by utilizing sub-micron colloidal debris. the consequences acquired function basic rules for info processing in small thermodynamic structures, and are acceptable to nanomachines and nanodevices.
