DNA nanostructures constitute attractive devices for logic computing and nanomechanics. An emerging interest is to integrate these two fields and devise intelligent DNA nanorobots. Here we report a reversible logic circuit built on the programmable assembly of a double-stranded (ds) DNA [3]pseudocatenane that serves as a rigid scaffold to position two separate branched-out head-motifs, a bimole...

A variable-length chromosome evolutionary algorithm for reversible circuit synthesis (VLEA RC) is presented to improve the quality of solutions in terms of quantum cost. The synthesis problem is formulated as a minimization problem with an equality constraint. To begin with, a modified stochastic ranking method for constraint handling is devised. This gives a better balance between decreasing t...

In recent years, research in the domain of reversible circuit design has attracted significant attention leading to many different approaches e.g. for synthesis, optimization, simulation, verification, and test. The open source toolkit RevKit is an attempt to make these developments publicly available to other researchers. For this purpose, a modular and extendable framework has been provided w...

Noise may play a pivotal role in gene circuit functionality, as demonstrated for the genetic switch in the bacterial phage lambda. Like the lambda switch, bacterial quorum sensing (QS) systems operate within a population and contain a bistable switching element, making it likely that noise plays a functional role in QS circuit operation. Therefore, a detailed analysis of the noise behavior of Q...

The current Very Large-Scale Integration (VLSI) technology has reached its peak due to the fundamental physical limits of Complementary Metal-Oxide-Semiconductor (CMOS). Quantum-dot Cellular Automata (QCA) is considered a proper alternative CMOS in digital circuit design. QCA features like low power, small area, and high speed nanoscale A code converter that converts determined another one. Cod...

Recently, reversible circuit synthesis has been intensively studied. One of the problems that has not been solved for a long time was exact minimization of gate count (GC) in 4-bit circuits. Finally, last year a tool of practical usage for finding optimal gate count Toffoli networks for any 4variable function was developed. However, not much work has been done yet on exact minimization of quant...

Reversible logic has attracted significant attention in recent years. It has applications in low power CMOS, quantum computing, nanotechnology, and optical computing. Traditional gates such as AND, OR, and EXOR are not reversible. In fact NOT is the only reversible gate from the traditional set of gates. Several reversible gates have been proposed. Among them are the controlled NOT (also known ...

The yield of adiabatic circuits strongly depends on the effects of parameter variations on the power dissipation. The dispersion of the threshold voltage has the most important impact on the yield. Different effects on the energy consumption due to interdie and intra-die variations of the threshold voltage are presented. Three logic families, the Efficient Charge Recovery Logic (ECRL), the Posi...
