Summary: This paper designed and simulated new structures based on a linear photonic crystal for realizing half-adder and half-subtractor. The transient analysis showed that the response time of the proposed devices is ultrafast. The small footprint and suitable contrast ratio make them usable for integration in ultrafast optical integrated circuits.

Summary: A versatile spatially controlled proximity split tweezer (PST) switch is developed for transducing diverse biomolecule signals into desired oligonucleotides. Leveraging the synergy between tweezer rigidity and hairpin lock, this strategy minimizes DNA circuit leakage. The platform enables logical operations and can be directly coupled with DNA catalytic circuits. Its design simplicity, flexibility, and expandable complexity offer broad applications in research and biomedicine.

Summary: In this study, two nano logical gates known as half-adder and subtractor were designed using the two-dimensional finite-difference time-domain method (FDTD) for the optical central processing unit in photonic computers. The gates consisted of a two-dimensional hexagonal lattice PC H-cavity as Kerr nonlinear photonic crystal structure along with a Mach-Zehnder modulator as bus waveguides, all based on plasmonic waveguides. The innovation of this designation lies in creating both gates using an identical geometric structure but only by changing the location of monitors and hard-wired sources into special intensities. The results showed that both gates achieved high transmission differences and ultrafast time response, and data transfer rate averaged at 4722.3 terabytes per second.

Summary: Conventional integrated circuits are limited by the interconnect bottleneck, but optical interchip communication provides a fast and energy-efficient alternative. By using metal plasmons as a platform, we have successfully created interconnect-free, ultracompact plasmonic Boolean logic gates that can be reconfigured into computing ALU at will, without the need for any redesign or cascaded circuitry.

Summary: In this paper, a novel design and three-dimensional simulation of a graphene-based integrated half adder using ring resonators and central waveguides have been presented. The logic of the half adder can be controlled by changing the Fermi voltage of graphene, and the output power is controlled at a central wavelength of 1550 nm. The extinction ratio and quality factor of the output resonators have been improved compared to other works, showing the effectiveness of the proposed structure.

Summary: This paper presents a novel design paradigm for implementing ternary logic circuits using GOTFETs and CNFETs, achieving higher performance and lower power consumption compared to traditional CMOS designs. By directly designing ternary logical functions and reducing transistor count and interconnects, the proposed circuits demonstrate significant improvements in terms of delay and power consumption. The introduced THA circuits show remarkable reductions in transistor count, delay, and power consumption compared to conventional CMOS designs.

Summary: The study focuses on the analysis of variability in memristor-based digital logic circuits, specifically on basic AND/OR Universal Logic Gates (ULG) and a Full adder implementation. A memristor's model is implemented and calibrated using data from IV curves of HfO2-based ReRAM. The results demonstrate that memristor variability affects the circuit's performance, despite the use of buffers to restore the signal.
