In this section of the study, we will discuss single-bit and single-qubit gates. These refer to 1-bit gates in classical computers and 1-qubit gates in quantum computers. Before making a swift transition to the topic, let us first address these concepts.

1-bit gates are gates that operate on a single bit in classical computing. For example, the digital NOT gate inverts the value of a single bit. In a scenario where the input is 0, this gate changes the input to 1, and if the input is 1, it changes it to 0.

1-qubit gates refer to quantum gates that operate on a single qubit in quantum computing. Quantum gates manipulate the superposition states of qubits. For instance, the X gate, also known as the quantum NOT gate, functions similarly to the classical NOT gate, but it can also invert quantum states.
