RGate#

class qiskit.circuit.library.RGate(theta, phi, label=None)[소스]#

기반 클래스: Gate

Rotation θ around the cos(φ)x + sin(φ)y axis.

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

Circuit symbol:

     ┌──────┐
q_0: ┤ R(ϴ) ├
     └──────┘

Matrix Representation:

\[ \begin{align}\begin{aligned}\newcommand{\th}{\frac{\theta}{2}}\\\begin{split}R(\theta, \phi) = e^{-i \th \left(\cos{\phi} x + \sin{\phi} y\right)} = \begin{pmatrix} \cos\left(\th\right) & -i e^{-i \phi} \sin\left(\th\right) \\ -i e^{i \phi} \sin\left(\th\right) & \cos\left(\th\right) \end{pmatrix}\end{split}\end{aligned}\end{align} \]

Create new r single-qubit gate.
