Instead of going with silicon-based switching (ie: transistors) this 4-bit adder uses mechanical ... to understand building blocks of logic structures like an adder. But there’s no better ...

Figure 3: Phototransistor and a hybrid logic gate. Figure 4: Voltage-switchable 2-bit adder and a 4-bit digital-to-analog converter. Hence, SWNT–Si junctions form a versatile platform for ...

Quantum gates are similar to classical logic gates, but their operations extend beyond binary bit manipulations to include ... implemented the FULL adder operation using CPU registers based ...
