# PulseLibraryItem

*class* `qiskit.qobj.PulseLibraryItem(name, samples)`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.4/qiskit/qobj/pulse_qobj.py#L533-L588)

Bases: [`object`](https://docs.python.org/3/library/functions.html#object)

An item in a pulse library.

Instantiate a pulse library item.

> **Deprecated since version 1.2**
>
> The class `qiskit.qobj.pulse_qobj.PulseLibraryItem` is deprecated as of qiskit 1.2. It will be removed in the 2.0 release. The Qobj class and related functionality are part of the deprecated BackendV1 workflow, and no longer necessary for BackendV2. If a user workflow requires Qobj it likely relies on deprecated functionality and should be updated to use BackendV2.

**Parameters**

- **name** ([*str*](https://docs.python.org/3/library/stdtypes.html#str)) – A name for the pulse.
- **samples** ([*list*](https://docs.python.org/3/library/stdtypes.html#list)*\[*[*complex*](https://docs.python.org/3/library/functions.html#complex)*]*) – A list of complex values defining pulse shape.
