Design of quantum cost efficient 4-bit reversible universal shift register

Heranmoy Maity, Arindam Biswas, Anup Kr. Bhattacherjee +1 more

This paper proposed the design of quantum cost efficient 4-bit reversible universal shift register(RUSR) using existing reversible logic gates. The proposed design is very useful in quantum computing due to its low quantum cost, less no. of reversible logic gate and low garbage outputs. The quantum cost(QC), garbage output(GO), number of gates are respectively 68, 20 and 16 for proposed work.

Quantum cost optimized design of 4-bit reversible universal shift register using reduced number of logic gate

Heranmoy Maity, Arindam Biswas, Anup Kumar Bhattacharjee +1 more

In this paper, we have proposed the design of quantum cost (QC) optimized 4-bit reversible universal shift register (RUSR) using reduced number of reversible logic gates. The proposed design is very useful in quantum computing due to its low QC, less no. of reversible logic gate and less delay. The QC, no. of gates, garbage outputs (GOs) are respectively 64, 8 and 16 for proposed work. The improvement of proposed work is also presented. The QC is 5.88% to 70.9% improved, no. of gate is 60% to 83.33% improved with compared to latest reported result.

Efficient Reversible Logic Design for Quantum Computing: A Novel 4-Bit LFSR Approach

N. Neelima, K. Nishanth Rao, Aruru Sai Kumar +3 more

Reversible logic gates are critical components in the field of quantum computing and low-power digital circuits, as they allow for the retrieval of input states from output states without any loss of information. This property ensures minimal energy dissipation, aligning with the principles of reversible computation. Their applications extend to quantum computing, cryptographic systems, and error detection and correction mechanisms. This paper presents a novel design for a Reversible D Flip-Flop (RDFF) and a 4-bit Linear Feedback Shift Register (LFSR). The Linear Feedback Shift Register (LFSR) is built utilizing four Register-Driven D Flip-Flops (RDFFs) and a feedback mechanism that incorporates a Feynman Gate. This configuration successfully showcases the capacity to generate pseudo-random sequences. The LFSR design demonstrates a 10% improvement in Total Reversible Logic Implementation Cost and 27% enhancement in quantum cost, making it a more resource-efficient option for reversible computing. This work makes a valuable contribution to the field of reversible computing by offering efficient designs for essential components.
