DynamicCircuitInstructionDurations.get#

DynamicCircuitInstructionDurations.get(inst, qubits, unit='dt', parameters=None)#

Get the duration of the instruction with the name, qubits, and parameters.

Some instructions may have a parameter dependent duration.

Deprecated since version 0.19.0: Using a Qubit or List[Qubit] for the qubits argument to InstructionDurations.get() is deprecated as of qiskit-terra 0.19.0. It will be removed no earlier than 3 months after the release date. Instead, use an integer for the qubit index.

Parameters:

  • inst (str | qiskit.circuit.Instruction) – An instruction or its name to be queried.

  • qubits (int | list[int] | Qubit | list[Qubit] | list[int | Qubit]) – Qubits or its indices that the instruction acts on.

  • unit (str) – The unit of duration to be returned. It must be ‘s’ or ‘dt’.

  • parameters (list[float] | None) – The value of the parameters of the desired instruction.

Returns:

The duration of the instruction on the qubits.

Return type:

float|int

Raises:

TranspilerError – No duration is defined for the instruction.
