PROJECT TITLE:

Design of Dedicated Reversible Quantum Circuitry for Square Computation - 2014

ABSTRACT:

Quantum computation is modeled by quantum circuits. All the quantum operations are reversible therefore the quantum circuits will be built using reversible logic gates. Reversible computing is the emerging technology, its major role is in the field of quantum computing, optical computing, and design of low power nanocircuits. The foremost frequently used computational unit for Digital Signal Processing and multimedia applications is multiplier. To compute sq. of an operand, regular multipliers are used in general. This project proposes a frenzied quantum circuit for computing sq. of an operand efficiently compared to the present multipliers in the literature. The squaring unit is mathematically modeled and its metrics quantum value, garbage outputs and ancilla input, gate count are calculated. We have a tendency to compared the proposed style with the prevailing multipliers to compute sq. and found that proposed sq. unit is efficient in terms of quantum cost, garbage outputs, ancilla inputs and gate count. The proposed reversible square circuit has sixty threep.c to eighty fivepercent improvement of quantum cost, garbage outputs, ancilla inputs and gate count over existing reversible multiplier circuits.
