A quantum logic gate is a basic quantum device that operates on a small number of quantum bits or qubits. A unitary matrix -- a square matrix of complex numbers -- represents the quantum gate. A 2nx2n ...

Quantum computers promise computations that no classical machine could match, but the qubits they run on are fragile things.

Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate—a NAND gate (short for "NOT AND")—in a soft material using only beams of ...

A single MXene-based optical gate switches between seven Boolean logic functions via voltage, enabling trainable photonic networks for AI tasks. (Nanowerk Spotlight) All-optical logic platforms are ...

In previous installments, we examined the different types of logic gates in detail, exploring their theoretical and practical applications. In this next part, we will dive into the practice of ...

The digital world offers many advantages over its analog relatives, the use of boolean logic among them. Some of the functions, like NOT, OR, and AND are fairly straightforward and line up nicely with ...
