Abstract:


Background:In this article, we have proposed a new reversible quantum circuit block along with the quantum cost (QC), constant input (CI), garbage output (GO) and delay optimized code converterusing quantum circuit block.

Method: Initially, new quantum circuit block has been designed and later reversible code converter circuits have been implemented using it. The proposed new quantum blockused to design 2’s complement code converter (2SCCC), cost efficient BCD to Excess-3 code converter (BECC) and can also be used to implement different logic functions. The QC of proposed quantum circuit block is 8. The QC and delay of the proposed 2SCCC is 8 and 1 respectively. Similarly, the QC and delay of the proposed BECC is 11 and 2 respectively. The proposed cost efficient BECC is designed using two NOT gate, one Feynman gate and one new quantum circuit block with QC is 11.

Results: The improvement of QC for 2SCCC and BECC are 27.27 % and 21.43% respectively. The improvement of delay for 2SCCC and BECC are 66.67% and 50% respectively compared with respect to the latest reported results.

Conclusion: So the improvement of QC and delay are very high using QCB.
