Methods

std::map<int, double> calculate_xeb_fidelity(
    GateType gt,
    Qubit* qbit0,
    Qubit* qbit1,
    const std::vector<int>& cycle_range,

    )

calculate xeb fidelity

Parameters:

GateType	gate type for calculating fidelity, must be double gate
Qubit*	qubit0
Qubit*	qubit1 , Must be adjacent to qubit0
const	std::vector<int>& the size of each layer
int	number of circuits of each layer
int	measure shot number

Returns:

std::map<int, double> xeb result of each layer
