Your First Gate

Every qubit in a fresh circuit starts in |0>. Your first job is the quantum version of flipping a bit: turn |0> into |1>.

Objective

flip_qubit() returns a one-qubit circuit that turns |0> into |1> and |1> back into |0>.

Constraints

• One gate is all you need.

Entry Point

Checks

• Exports flip_qubit().
• Turns |0> into |1>.
• Turns |1> back into |0>.
