We analyze a quantum network, constructed with ballistic electron waveguides, which can add one-bit binary numbers. We consider two different adder networks, one constructed with Hadamard gates and the other constructed with ÎNOT gates. Reflection of electron probability at the gates causes a loss in fidelity of the overall calculation. A fidelity requirement for the implementation of individua...

The purposes to use quality gates in software development are many. Quite often companies see that the usage of quality gates improves their overall efficiency, effectiveness and output quality of software delivery chain. They also see that the usage of quality gates helps them to make things right at once by not skipping quality assurance actions. This paper defines quality gate model for a so...

Attribute gates are a new user interface element designed to address the problem of concurrently setting attributes and moving objects between territories on a digital tabletop. Motivated by the notion of task levels in activity theory, and crossing interfaces, attribute gates allow users to opera-tionalize multiple subtasks in one smooth movement. We present two configurations of attribute gat...

A thorough investigation has been made to obtain SQUID device parameters and properties, and the optimization of the latter for the application of logics gates. SQUID OR, AND gates have been designed theoretically using the optimized techniques. Our concept of turn-on delay has been applied for critically ascertaining the switching speed of these logic gates. The dynamic response of the logics ...

New techniques for reducing the depth of circuits for cryptographic applications are described and applied to the AES S-box. These techniques also keep the number of gates quite small. The result, when applied to the AES S-box, is a circuit with depth 16 and only 128 gates. For the inverse, it is also depth 16 and has only 127 gates. There is a shared middle part, common to both the S-box and i...

We describe a high-speed physical random number generator based on a hybrid Boolean network with autonomous and clocked logic gates, realized on a reconfigurable chip. The autonomous logic gates are arranged in a bidirectional ring topology and generate broadband chaos. The clocked logic gates receive input from the autonomous logic gates so that random numbers are generated physically that pas...

residual microorganisms in the root canal system (rcs) after endodontic therapy such as candida albicans are a major cause of endodontic failure. calcium hydroxide (ch) and chlorhexidine (chx) have suitable antimicrobial activity against bacteria and can be used as intracanal medicaments. nanosilver has also shown antimicrobial activity against microorganisms. this study aimed to compare the an...

We propose a new class of unconventional geometric gates involving nonzero dynamic phases, and elucidate that geometric quantum computation can be implemented by using these gates. Comparing with the conventional geometric gate operation, in which the dynamic phase shift must be removed or avoided, the gates proposed here may be operated more simply. We illustrate in detail that unconventional ...

This paper describes the fabrication, characterization and modeling of fundamental logic gates that can be used for designing biosensors with embedded forward error-correction (FEC). The proposed logic gates (AND and OR) are constructed by patterning antibodies at different spatial locations along the substrate of a lateral flow immunosensor assay. The logic gates operate by converting binding ...
