In traditional computing, these gates are made using transistors, which are semiconductor devices that can switch electronic signals on and off.

Traditional transistors are designed to perform predetermined logical functions, while RFETs are used to build circuits with functions that can be programmed on the go.

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is ...

July 16, 2019 Researchers build transistor-like gate for quantum information processing – with qudits Two-qudit gate on a photonic platform achieves massive entangled quantum state A two-qudit gate, ...

Using an old chessboard, eyelets, rings, weights, and string, [Alex] has designed a system that can show off all of the logic gates. This includes: NOT, BUFFER, NAND, AND, OR, NOR, XOR, XNOR.
