To attain such design architecture, SWAP gates plays a significant role of bringing the qubits to adjacent locations. But this in turn introduces design overhead so NN-based realization using limited number of SWAP gates has become significant. In order to explore this area, in this article, we introduced an efficient design technique for NN realization of quantum circuits in 2D architecture. The design algorithm has been partitioned into three phases of qubit selection, qubit placement and SWAP gate implementation.
To verify the exactness of the stated design approach, its functionality has been evaluated over a wide set of benchmark function and subsequently witnessed an improvement on its cost metrics. Bhattacharjee, C. Bandyopadhyay, B. The reversible logic is a promising technology for zero power dissipation. The reversible logic circuits are realized in quantum cellular automata QCA , which are called as quantum circuits.
The router is a predominant device in the modern communication era. The router is expected to perform faster with minimum area requirement and power consumption. In this paper, a nano router is designed in reversible logic and it is realized in quantum cellular automata. The memory plane and the routing data plane are the major functional components of the router.

These are constructed from the basic peripherals decoder, memory array, multiplexer, switch fabric and parallel-to-serial converter. The constructed router peripherals are combined together to form the integrated router and it is realized in QCA. The QCA realized structure has the significance of multilayer crossing for its wire crossing.
The multilayer crossing reduces the number of cells required for realization and also it passes the signal without any degradation. The nano router is suitable for nano-communication applications. The realization is performed in QCADesigner tool. Kamaraj, P. Marichamy, J.
Senthil Kumar, S. Selva Nidhyananthan, C. Kalyana Sundaram. At nanoscale, for digital systems, the device density and power constraint of the circuit are essential issues. Quantum-dot cellular automata QCA is an incipient nanotechnology, which leads to build circuits at nanoscale. It offers various features such as minimal power dissipation, very high-operating frequency, and nanoscale feature size. Besides, reversible computation can lead to the development of low-power systems without loss of information.
Thus, reversible QCA logic can provide a powerful and efficient computing platform for digital applications. This paper presents a QCA code converter. Feynman gate is used as a fundamental building block to perform the proposed design of code converter. QCADesigner version 2. QCAPro, a very widespread power estimator simulation engine, is applied to estimate the power depletion of the proposed circuit. Titel Design and Testing of Reversible Logic.
Print ISBN Electronic ISBN Research related to floating-point computation spans a multitude of areas of computer science, ranging from hardware design and architecture, all the way to high-performance computing, machine learning, and software analysis and verification.
The focus of this Dagstuhl Seminar is to connect researchers from these areas, with the goals of fostering collaboration, and brainstorming new theoretical advances, practical techniques and tools to improve the reliability and performance of floating-point computation. There has been a lot of recent interest in floating-point optimization and reasoning, including expression rewriting and instruction generation to improve precision; abstract interpretation, automated theorem proving, SMT solving and global optimization for rigorous reasoning; and integration of lower-precision computations into floating-point programs to conserve energy while achieving acceptably stable results important in high-performance computing and machine learning.

While these above approaches and techniques have certainly advanced the current state-of-the-art, they still suffer from various drawbacks, such as limited automation, precision, or scalability, which prevents them from being transferred into practical solutions. Much more work is needed, including breakthroughs that include completely novel techniques as well as novel combinations of existing methods.
For example, covalent electronic chemistry would be used to make the building blocks, followed by noncovalent assembly of the building blocks into larger structures. Of course, this is research that is being done already, but without the kind of real-time instrumental monitoring and control needed to achieve optimum results. Atomic layer deposition and molecular beam epitaxy MBE are atomic-level equivalents of additive manufacturing AM at the macroscale. Hierarchical synthesis processes that have not traditionally been viewed as kinetic processes, such as self-assembly, should be considered as such; the fact that they are driven by thermodynamics does not mean they do not have kinetic trajectories often sluggish ones.
Kinetically stabilized and metastable phases may be the desired product. A wide variety of materials types will be incorporated into one finished product, necessitating wider understanding or, more likely, collaboration on the part of the synthesizers, in order to master the creation of these materials.
DNA origami is the folding of a long strand of DNA, the scaffold, into nanoscale objects through the use of short-chain DNA oligonucleotides, the so-called strands. The past decade has seen significant advances in the design toolbox to build 3D structures, and with each development the number of degrees of freedom increases and this enables construction of more intricate shapes.

The first approach to 3D structures was achieved by bundling DNA helices in a honeycomb structure. Curved objects were achieved by adding or deleting the strands between the helical scaffold bundles. Another approach involved the use of curved rings to enable control of the shape.
Design and Testing of Reversible Logic
From the bundled helical structures came wire-frame designs in either a grid-iron pattern or triangular mesh. This advance has important implications for biomedical applications because structures created through these approaches offer higher resistance to cation depletion under physiological conditions. Ke, L. Ong, W. Shih, and P. Yin, , Three-dimensional structures self-assembled from DNA bricks, Science , doi: The origami structures have been used as templates for producing Au nanoparticles, Au nanorods, and quantum dots; molds in which to synthesize nanoparticles; meshes for microlithography; and biosensors; and for drug delivery.
In addition, active systems, walkers, machines, and factories have already been demonstrated on origami platforms. Furthermore, it was demonstrated that origami was possible with long-chain RNA scaffolds. A class of reconfigurable metamaterials that has advanced considerably over the past decade is one based on 2D films that fold or bend into predetermined 3D structures.
These materials have potential applications to biomedical devices e. Advances in the ability to fabricate 3D structures at the micro- and nanolength scales were achieved. Other approaches to develop 3D nanostructures exploit bending and folding of thin plates by the actions of residual stresses or capillarity effects and self-actuating materials. It is also possible to generate 3D structures that respond to an external stimulus such as heat or water. Origami folding and kirigami cutting and folding -inspired designs have expanded the structures that can be formed and increased the materials space to include important ones needed for future advanced technologies.
An example of the processing of a mechanically guided scheme is shown schematically in Figure 4. The formation of robust 3D structures requires minimization of the overall strain as well as the formation of strain concentrations. The minimization of the strain has been achieved through the use of finite element modeling, which has shown that the length and width of the kirigami cut are important.
It turns out that longer cuts are better than shorter ones, as stress concentrations are avoided, and wider. Gu, J. Chao, S. Xiao, and N.
