• Defined in File SingleQubitGateHelper.hpp

Class Documentation

template<SingleQubitGateWithParam AVXImpl, typename ParamT>
class SingleQubitGateWithParamHelper

A Helper class for single-qubit gates with parameters.

Public Types

using Precision = typename AVXImpl::Precision

using ReturnType = typename FuncReturn<decltype(AVXImpl::template applyExternal<ParamT>)>::Type

using FuncType = ReturnType (*)(std::complex<Precision>*, size_t, const std::vector<size_t>&, bool, ParamT)

Public Functions

inline explicit SingleQubitGateWithParamHelper(FuncType fallback_func)

inline auto operator()(std::complex<Precision> *arr, const size_t num_qubits, const std::vector<size_t> &wires, bool inverse, ParamT angle) const -> ReturnType

This function calls corresponding AVX2/512 kernel functions by finding the correct one based on wires.

Parameters

• arr – Pointer to a statevector array

• num_qubits – Number of qubits

• wires – Wires the gate applies to

• inverse – Apply the inverse of the gate when true

• angle – Parameter of the gate
