Barrier

class Barrier(num_qubits)

GitHub

Bases: qiskit.circuit.instruction.Instruction

Barrier instruction.

Create new barrier instruction.


Methods Defined Here

broadcast_arguments

Barrier.broadcast_arguments(qargs, cargs)

Validation of the arguments.

Parameters

  • qargs (List) – List of quantum bit arguments.
  • cargs (List) – List of classical bit arguments.

Yields

Tuple(List, List) – A tuple with single arguments.

Raises

CircuitError – If the input is not valid. For example, the number of arguments does not match the gate expectation.

c_if

Barrier.c_if(classical, val)

Add classical condition on register or cbit classical and value val.

inverse

Barrier.inverse()

Special case. Return self.

definition

Return definition in terms of other basic gates.

duration

Get the duration.

label

Return instruction label

Return type

str

params

return instruction params.

unit
