Collision-based reaction-diffusion computing (RDC) represents information quanta as traveling chemical wave fragments on an excitable medium. Although the medium’s computational ability is certainly increased by utilizing its spatial degrees of freedom [2], our interpretation of collision-based RDC in this paper is that wave fragments travel along ‘limited directions’ ‘instantaneously’ as a res...

The paper describes the design of programmable reversible logic gate structures, targeted for the ALU implementation and their use in the realization of an efficient reversible ALU. Using reversible logic gates instead of traditional logic AND/OR gates, a reversible ALU whose function is the same as traditional ALU is constructed. Comparing with the number of input bits and the discarded bits o...

Over the last few decades, research in reversible logic has increasingly become very popular and it is gaining greater momentum in the present word. Reversible logic has started finding concert applications in quantum computing, optical computing, nano-technology based system, low-power CMOS design, VLSI design. The principal objective of this work is to argue for quantum implementation of vari...

One limit on developing complex synthetic gene circuits is the lack of basic components such as transcriptional logic gates that can process combinatorial inputs. Here, we propose a strategy to construct such components based on reusable designs and convergent reengineering of well-studied natural systems. We demonstrated the strategy using variants of the transcription factor (TF) LacI and ope...

One fascinating recent avenue of study in the field of synthetic biology is the creation of biomolecule-based computers. The main components of a computing device consist of an arithmetic logic unit, the control unit, memory, and the input and output devices. Boolean logic gates are at the core of the operational machinery of these parts, and hence to make biocomputers a reality, biomolecular l...

We present conceptual models for fundamental logic gates using solitons as bit pulses in the Toda lattice. The transmission rate of the soliton is controllable by another soliton and the control of the soliton transmission is applicable to a NOT gate. Two-input system with appropriate transmission filters were constructed to realize AND and OR gates. We numerically demonstrated the soliton tran...

This paper presents some simple ideas about domino gates. Domino gates are implementations of logical operations using toppling dominoes to represent the movement of information (bits). The actively toppling domino represents a logic one, and absence of toppling represents logic zero. The domino model can be used as a representation of single-shot wave gates in unconstrained media, such as sub-...

Reversible logic gates are very much in demand for the future computing technologies as they are known to produce zero power dissipation under ideal conditions. The applications of reversible logic gates include ultralow power, nano computing, quantum computing, low power CMOS design, optical information processing, bioinformatics etc. This paper proposes an improved design of a multiplier usin...

Reversible logic plays an important role in quantum computing. Several papers have been recently published on universality of sets of reversible gates. However, a fundamental unsolved problem remains: “what is the minimum set of gates that are universal for n-qubit circuits without ancillae bits”. We present a library of 2 gates which is sufficient to realize all reversible circuits of n variab...

The paper deals with the problem of designing digital circuits with the currentmode gates novel digital gates operating with constant, continuous power supply current. The purpose is the provision of a high level of noise immunity of the chips which compose both analog and digital circuits. The logical properties of the current-mode gates and logic (algebra) are investigated, which are a base t...
