Logical variable. Set true to write output messages to the 'debug.txt' file.

Definition at line 53 of file logging.h.

◆ debugfile_name

std::string logging::debugfile_name

inherited

String variable. Set the debug file name.

Definition at line 56 of file logging.h.

◆ matrix_size

int Gate::matrix_size

protectedinherited

The size N of the NxN matrix associated with the operations.

Definition at line 106 of file Gate.h.

◆ name

std::string Gate::name

protectedinherited

A string labeling the gate operation.

Definition at line 92 of file Gate.h.

◆ parameter_num

int Gate::parameter_num

protectedinherited

the number of free parameters of the operation

Definition at line 108 of file Gate.h.

◆ parameter_start_idx

int Gate::parameter_start_idx

protectedinherited

the index in the parameter array (corrensponding to the encapsulated circuit) where the gate parameters begin (if gates are placed into a circuit a single parameter array is used to execute the whole circuit)

◆ parents

std::vector<Gate*> Gate::parents

protectedinherited

list of parent gates to be applied in the circuit prior to this current gate

Definition at line 112 of file Gate.h.

◆ qbit_num

int Gate::qbit_num

protectedinherited

number of qubits spanning the matrix of the operation

Definition at line 94 of file Gate.h.

◆ target_qbit

int Gate::target_qbit

protectedinherited

The index of the qubit on which the operation acts (target_qbit >= 0)

Definition at line 98 of file Gate.h.

◆ target_qbits

std::vector<int> Gate::target_qbits

protectedinherited

Vector of target qubit indices (for multi-qubit gates)

Definition at line 102 of file Gate.h.

◆ type

gate_type Gate::type

protectedinherited

The type of the operation (see enumeration gate_type)

Definition at line 96 of file Gate.h.

◆ verbose

int logging::verbose

inherited

Set the verbosity level of the output messages.

Definition at line 50 of file logging.h.
