qiskit.circuit.QuantumCircuit.append

QuantumCircuit.append(instruction, qargs=None, cargs=None)

Append one or more instructions to the end of the circuit, modifying the circuit in place.

The qargs and cargs will be expanded and broadcast according to the rules of the given Instruction, and any non-Bit specifiers (such as integer indices) will be resolved into the relevant instances.

If a CircuitInstruction is given, it will be unwrapped, verified in the context of this circuit, and a new object will be appended to the circuit. In this case, you may not pass qargs or cargs separately.

Parameters

• instruction (Operation | CircuitInstruction) -- Instruction instance to append, or a CircuitInstruction with all its context.

• qargs (Sequence[QubitSpecifier] | None) -- specifiers of the Qubits to attach instruction to.

• cargs (Sequence[ClbitSpecifier] | None) -- specifiers of the Clbits to attach instruction to.

Returns

a handle to the CircuitInstructions that were actually added to the circuit.

Return type

qiskit.circuit.InstructionSet

Raises

CircuitError -- if the operation passed is not an instance of Instruction .
