Can flipping a coin change its outcome?

Imagine flipping a coin that always lands on heads. You want it to land on tails instead.

Think of a coin flip as a qubit in quantum computing. The Pauli-X gate is like a magic trick that flips the coin from heads (|0⟩) to tails (|1⟩) or vice versa.

Example

If the coin (qubit) is heads (|0⟩), applying the magic trick (Pauli-X gate) makes it tails (|1⟩).

Remember this

The Pauli-X gate flips a qubit's state like a magic trick flips a coin.
