Beschreibung
The elementary logic gates of a classical computer, other than the NOT gate, are not reversible. Thus, for instance, for an AND gate one cannot recover the two input bits from the output bit; for example, if the output bit is 0, we cannot tell from this whether the input bits are 0,1 or 1,0 or 0,0. However, reversible gates in classical computers are easily constructed for bit strings of any length; moreover, these are actually of practical interest, since they do not increase entropy. A reversible gate is a reversible function on n-bit data that returns n-bit data, where an n-bit data is a string of bits x1,x2,.,xn of length n. The set of n-bit data is the space {0, 1}n, which consists of 2n strings of 0's and 1's.spintronics (a portmanteau meaning spin transport electronics also known as spinelectronics or fluxtronics, is the study of the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices.Spintronics differs from the older magnetoelectronics, in that spins are manipulated by both magnetic and electrical fields. This book is systematic representation of the future electronic.
