Optical half-adder and half-subtracter employing the Pockels effect.
The Pockels effect in periodically poled lithium niobate made it possible to switch optical signals between two orthogonal optical linear polarizations of the vertical and horizontal polarization states. Based on this effect, we demonstrated polarization-based binary optical logic gates: AND, and OR gates. By combining these basic gates with other polarization-based optical logic gates such as ...
متن کاملDeoxyribozyme-based half-adder.
We have constructed a solution-phase array of three deoxyribozyme-based logic gates that behaves as a half-adder. Two deoxyribozymes mimic i(1)ANDNOTi(2) and i(2)ANDNOTi(1) gates that cleave a fluorogenic substrate, reporting through an increase in fluorescence emission at 570 nm. The third deoxyribozyme mimics an i(1)ANDi(2) gate and cleaves the other fluorogenic substrate, reporting through a...
متن کاملMolecular beacon-based half-adder and half-subtractor.
This work demonstrates two DNA-based logic circuits that behave as a half-adder and a half-subtractor. A half-adder is composed of an AND gate and an XOR gate, whereas a half-subtractor consists of an INH gate and an XOR gate. The proposed designs are inspired by molecular beacons.
متن کاملHigh-Speed Ternary Half adder based on GNRFET
Superior electronic properties of graphene make it a substitute candidate for beyond-CMOSnanoelectronics in electronic devices such as the field-effect transistors (FETs), tunnel barriers, andquantum dots. The armchair-edge graphene nanoribbons (AGNRs), which have semiconductor behavior,are used to design the digital circuits. This paper presents a new design of ternary half a...
متن کاملQuantum half-adder
Implementation of a linear optics quantum multibit half-adder that could show potential scalability is discussed. Parametric down-conversion sources are assumed that are pumped by a mode carrying orbital angular momentum l. A single photon from a pair is prepared by detection of its twin. This preparation of a single photon defines two bits to be summed and the starting carry control bit. This ...
