In quantum computing and specifically the quantum circuit model of computation, a quantum logic gate (or simply quantum gate) is a basic quantum circuit operating on a small number of qubits. Quantum logic gates are the building blocks of quantum circuits, like classical logic gates are for conventional digital circuits.
Mar 21, 2018 · Logic gates are building blocks for processing information. One kind of logic gate, known as the AND gate, could, for example, quickly determine whether two people agree to a business deal. It takes in two bits of information, and generates a 1 if both incoming bits are 1s.
Jan 30, 2024 · Major quantum logic gates include the Hadamard gate, the Pauli-X gate, the Pauli-Y gate, and the Pauli-Z gate. These gates are used to create complex quantum circuits that can perform calculations much faster than classical computers.
Mar 18, 2024 · Nature Communications - Ensuring high-fidelity quantum gates while increasing the number of qubits poses a great challenge. Here the authors present a scalable strategy for optimizing frequency...
Here, we report the implementation of super-compact universal quantum logic gates on silicon chips by the method of inverse design. In particular, the fabricated controlled-NOT gate and Hadamard gate are both nearly a vacuum wavelength, being the smallest optical quantum gates reported up to now.

Feb 26, 2018 · A logic gate, whether classical or quantum, is any physical structure or system that takes a set of binary inputs (whether 0s and 1s, apples and oranges, spin-up electrons and spin-down electrons, you name it) and spits out a single binary output: a 1, an orange, a spin-up electron, or even one of two states of superposition.
