PAULI‒Y GATE (Y GATE)

Definition

The Pauli‒Y gate is a single‒qubit quantum gate that flips the qubit state while adding a phase factor. It transforms |0> into i|1> and |1> to ‒i|0>.

Action

Introduces a phase and flips the qubit with a phase shift

Matrix form

The matrix for the Y gate is the same as Pauli matrix σ_y and can be written as

Operation

Y |0> = i|1>

Y |1> = -i|1>

Bloch Sphere action

Rotation by π radians (180°) around the Y‒axis
