RYGate

class RYGate(theta, label=None)

Bases: qiskit.circuit.gate.Gate

Single-qubit rotation about the Y axis.

Circuit symbol:

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

Matrix Representation:

\providecommand{\th}{\frac{\theta}{2}}\\\begin{split}RY(\theta) = exp(-i \th Y) = \begin{pmatrix} \cos{\th} & -\sin{\th} \\ \sin{\th} & \cos{\th} \end{pmatrix}\end{split}

Create new RY gate.

Methods Defined Here

RYGate.control(num_ctrl_qubits=1, label=None, ctrl_state=None)

Return a (multi-)controlled-RY gate.

Parameters

num_ctrl_qubits (int) – number of control qubits.
label (str or None) – An optional label for the gate [Default: None]
ctrl_state (int or str or None) – control state expressed as integer, string (e.g. ‘110’), or None. If None, use all 1s.

Returns

controlled version of this gate.

Return type

ControlledGate

RYGate.inverse()

Return inverted RY gate.

$RY(\lambda){\dagger} = RY(-\lambda)$

Get the decompositions of the instruction from the SessionEquivalenceLibrary.

Return definition in terms of other basic gates.

Get the duration.

Return instruction label

Return type

str

return instruction params.

Get the time unit of duration.
