Class Documentation

template<SingleQubitGateWithoutParam AVXImpl>
class SingleQubitGateWithoutParamHelper

A Helper class for single-qubit gates without parameters.

Public Types

using Precision = typename AVXImpl::Precision

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

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

Public Functions

inline explicit SingleQubitGateWithoutParamHelper(FuncType fallback_func)

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