Class Documentation

template<class AVXImpl, class ParamT>
class TwoQubitGateWithParamHelper

A helper class for two-qubit gate without parameters.

Public Types

using Precision = typename AVXImpl::Precision

using ReturnType = typename FuncReturn<decltype(AVXImpl::template applyExternalExternal<Precision>)>::Type

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

Public Functions

inline explicit TwoQubitGateWithParamHelper(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, ParamT angle) const -> ReturnType
requires SymmetricTwoQubitGateWithParam<AVXImpl>

A specialization for symmetric two-qubit gates (control and target wires are symmetric), which calls the correct AVX2/512 kernel functions 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

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

A specialization for asymmetric two-qubit gates (control and target wires are asymmetric), which calls the correct AVX2/512 kernel functions 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
