RZGate

class RZGate(phi, label=None)

ベースクラス: Gate

Single-qubit rotation about the Z axis.

This is a diagonal gate. It can be implemented virtually in hardware via framechanges (i.e. at zero error and duration).

Can be applied to a QuantumCircuit with the rz() method.

Circuit symbol:

     ┌───────┐
q_0: ┤ Rz(λ) ├
     └───────┘

Matrix Representation:

\[\begin{split}RZ(\lambda) = \exp\left(-i\frac{\lambda}{2}Z\right) = \begin{pmatrix} e^{-i\frac{\lambda}{2}} & 0 \\ 0 & e^{i\frac{\lambda}{2}} \end{pmatrix}\end{split}\]

参考

U1Gate This gate is equivalent to U1 up to a phase factor.

\[U1(\lambda) = e^{i{\lambda}/2}RZ(\lambda)\]
