Polymorphic digital circuits are circuits composed of polymorphic (multifunctional) as well as ordinary gates. In addition to its standard logic function (such as NAND), a polymorphic gate exhibits another logic function which is activated under a specific condition, for example, when Vdd, temperature, illumination or a special signal reaches a certain level. This paper describes existing polym...

Abstract: In today’s world power dissipation is the main problem in digital world; this problem can be reduced by using reversible logic gates. For high performance systems, low power and smaller area are the most important criteria. Area and speed are main factors which are conflicting i.e. if speed is improving it results in larger area, hence in this paper reversible logic gates are analyzed...

We extend the circuit model of quantum computation so that wiring between gates is soft-coded within registers inside gates. The addresses in these can be manipulated and put into superpositions. This aims at capturing indefinite causal orders making their geometrical layout explicit: we express switch polarizing beam-splitter model. In this context, our main contribution a full characterizatio...

Due to its fault-tolerant gates, the Clifford+T library consisting of Hadamard (denoted by H), T , and CNOT gates has attracted interest in the synthesis of quantum circuits. Since the implementation of T gates is expensive, recent research is aiming at minimizing the use of such gates. It has been shown that T -depth optimizations can be implemented efficiently for circuits consisting only of ...
