Template Function Pennylane::Gates::getRot

• Defined in File Gates.hpp

Function Documentation

template<template<typename...> class ComplexT, typename T, typename U = T>
static auto Pennylane::Gates::getRot(U phi, U theta, U omega) -> std::vector<ComplexT<T>>

Create a matrix representation of the Rot gate data in row-major format.

The gate is defined as: $\begin{split}Rot(\phi,\theta,\omega) = RZ(\omega)RY(\theta)RZ(\phi)= \begin{bmatrix} e^{-i(\phi+\omega)/2}\cos(\theta/2) & -e^{i(\phi-\omega)/2}\sin(\theta/2) \\ e^{-i(\phi-\omega)/2}\sin(\theta/2) & e^{i(\phi+\omega)/2}\cos(\theta/2) \end{bmatrix}.\end{split}$

Template Parameters

• ComplexT – Complex class.

• T – Required precision of gate (float or double).

• T – Required precision of parameter (float or double).

Parameters

• phi – $\phi$ shift angle.

• theta – $\theta$ shift angle.

• omega – $\omega$ shift angle.

Returns

std::vector<ComplexT<T>> Return Rot gate data.
