RYGate¶

class RYGate(theta, label=None)[source]¶

Bases: Gate

Single-qubit rotation about the Y axis.

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

Circuit symbol:

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

Matrix Representation:

\[ \begin{align}\begin{aligned}\newcommand{\th}{\frac{\theta}{2}}\\\begin{split}RY(\theta) = \exp\left(-i \th Y\right) = \begin{pmatrix} \cos\left(\th\right) & -\sin\left(\th\right) \\ \sin\left(\th\right) & \cos\left(\th\right) \end{pmatrix}\end{split}\end{aligned}\end{align} \]

Create new RY gate.
