Reversibility plays a fundamental role when computations with minimal energy dissipation are considered. In recent years, reversible logic has emerged as one of the most important approaches for power optimization with its application in low power CMOS, optical information processing, quantum computing and nanotechnology. This research proposes a new implementation of Binary Coded Decimal (BCD)...

A three-component molecular ensemble consisting of the constitutionally dynamic cage 1, rotaxane 2 and luminophore 3 acts as a signal transducer which assimilates three input signals, i.e., Zn2+, H+, Cu+, to perform individual logic operations (e.g. 3-input NOR gate with catalytic output, AND optical output ) operates an unconventional demultiplexer .

Chaotic systems can yield a wide variety of patterns. Here we use this feature to generate all possible fundamental logic gate functions. This forms the basis of the design of a dynamical computing device, a chaogate, that can be rapidly morphed to become any desired logic gate. Here we review the basic concepts underlying this and present an extension of the formalism to include asymmetric log...

Surface plasmon polaritons (SPPs) may serve as ultimate data processing expedients in future nanophotonic applications. SPPs combine the high localization of electrons with the bandwidth, frequency and propagation properties of photons, thus supplying nature with the best of two worlds. However, although plasmonics have recently gained constantly growing scientific attention, logic devices that...
