Gate

Beginner Gates ⭐ Featured
A basic operation on qubits that transforms their quantum state, analogous to logic gates in classical computing.

📖 In-Depth Explanation

Quantum gates are reversible unitary operations. Common single-qubit gates include X (NOT), Y, Z, Hadamard (H), and rotation gates. Two-qubit gates like CNOT enable entanglement.
