How the Pauli-X Gate Works ? Quantum Computing Basics

[00:00:00]The Pauli X gate. The Pauli X gate is the quantum version of the classical not gate. Its job is simple, to flip the state of a qubit. If the qubit is in state zero wrangle, it becomes one wrangle. And if it is in state one wrangle, it becomes zero wrangle.

[00:00:16]To visualize this, think of the Pauli X gate as a light switch. If the switch is off, the X gate turns it on. If it is on, the X gate turns it off. In quantum computing, this means changing the qubit from zero to one or from one to zero.

[00:00:30]Because it is one of the most fundamental quantum gates, the X gate is used whenever we need to flip a qubit's value during a quantum computation.
