The Phase gate turns a |0> into |0> and a |1> into i|1>.
PHASE GATE
Definition
The
Phase gate turns a |0> into |0> and a |1> into i|1>.
Action
(i)
A Phase Gate acts only on the |1> state of a qubit by adding a phase factor,
while leaving the |0> state unchanged.
Matrix form
The
matrix for the phase gate can be defined as
Operation
Bloch Sphere action
Phase
Gate (also called a Z‒rotation gate) performs a rotation around the Z‒axis of
the Bloch sphere.
Property
A
Z gate can be obtained by connecting two S gates in series
