• Defined in File MeasuresFunctors.hpp

Class Documentation

template<class PrecisionT, class DeviceType, std::size_t num_wires>
class getProbsNQubitOpFunctor

Compute probability distribution from StateVector.

Template Parameters

• PrecisionT – StateVector precision.

• DeviceType – Kokkos execution space.

• num_wires – Number of wires (0 is used for a dynamic number of wires).

Param arr_

StateVector data.

Param num_qubits_

Number of qubits.

Param wires_

Wires for which the probability is computed.
