A Novel Approach for Implementing LFSRs Using QCA Technology

Quantum random number generators have attracted the research community for providing secure communication. This paper presents a novel Quantum LFSR, designed using the novel construction of D-Flip-Flop (DFF) and XOR gates in QCA. The suggested Quantum LFSR comprises 216 cells with an area of 0.23μm2 and the total power dissipation is 0.31442 eV, 0.41729 eV, and 0.54389 eVat different standard tunnelling energy levels. The power parameters are analysed using QCA Pro, and the calculated outcomes show that the Quantum LFSR has low power consumption and reduced footprint compared to conventional designs.
