RXGate

class RXGate(theta, label=None)

Single-qubit rotation about the X axis.

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

Circuit symbol:

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

Matrix Representation:

\providecommand{\th}{\frac{\theta}{2}}\\\begin{split}RX(\theta) = \exp\left(-i \th X\right) = \begin{pmatrix} \cos{\th} & -i\sin{\th} \\ -i\sin{\th} & \cos{\th} \end{pmatrix}\end{split}

Create new RX gate.

Methods Defined Here

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

Return a (multi-)controlled-RX 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
