In this article, we will explore the fundamentals of quantum gates and discuss how to implement control on them.
Quantum gates are the quantum analogs of classical logic gates. They are the basic building blocks of quantum circuits and are used to manipulate qubits, the basic units of quantum information. The most common types of quantum gates are the Pauli gates, Hadamard gate, phase gate, and the CNOT gate.

What is controlling a gate in quantum computing?
Controlling a gate in quantum computing is the process of using a control qubit to manipulate the state of a target qubit.
