# qiskit.providers.aer.library.save\_probabilities\_dict
<Function id="qiskit.providers.aer.library.save_probabilities_dict" isDedicatedPage={true} github="https://github.com/qiskit/qiskit-aer/tree/stable/0.9/qiskit/providers/aer/library/save_instructions/save_probabilities.py" signature="save_probabilities_dict(self, qubits=None, label='probabilities', unnormalized=False, pershot=False, conditional=False)">
Save measurement outcome probabilities vector.
**Parameters**
* **qubits** (*list or None*) the qubits to apply snapshot to. If None all qubits will be snapshot \[Default: None].
* **label** (*str*) the key for retrieving saved data from results.
* **unnormalized** (*bool*) If True return save the unnormalized accumulated probabilities over all shots \[Default: False].
* **pershot** (*bool*) if True save a list of probabilities for each shot of the simulation rather than the average over all shots \[Default: False].
* **conditional** (*bool*) if True save the probabilities data conditional on the current classical register values \[Default: False].
**Returns**
with attached instruction.
**Return type**
[QuantumCircuit](qiskit.circuit.QuantumCircuit "qiskit.circuit.QuantumCircuit")
