Quantum logic gate

ID: quantum-logic-gate

A quantum logic gate is a fundamental building block of quantum computing, analogous to classical logic gates in traditional computing. Quantum gates manipulate individual qubits (quantum bits), which are the basic units of quantum information. Unlike classical bits that can exist in a state of either 0 or 1, qubits can exist in superpositions of these states, allowing for a more complex form of computation.

At Section "Quantum computing is just matrix multiplication" we saw that making a quantum circuit actually comes down to designing one big unitary matrix.
We have to say though that that was a bit of a lie.
Quantum programmers normally don't just produce those big matrices manually from scratch.
Instead, they use quantum logic gates.
