HGate¶

class HGate(label=None)[Quellcode]¶

Bases: Gate

Single-qubit Hadamard gate.

This gate is a pi rotation about the X+Z axis, and has the effect of changing computation basis from \(|0\rangle,|1\rangle\) to \(|+\rangle,|-\rangle\) and vice-versa.

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

Circuit symbol:

     ┌───┐
q_0: ┤ H ├
     └───┘

Matrix Representation:

\[\begin{split}H = \frac{1}{\sqrt{2}} \begin{pmatrix} 1 & 1 \\ 1 & -1 \end{pmatrix}\end{split}\]

Create new H gate.

Methods Defined Here

`control`	Return a (multi-)controlled-H gate.
`inverse`	Return inverted H gate (itself).
