DataBin

class qiskit.primitives.DataBin(*, shape=(), **data)

Bases: ShapedMixin

Namespace for storing data.

import numpy as np
from qiskit.primitives import DataBin, BitArray

data = DataBin(
    alpha=BitArray.from_samples(["0010"]),
    beta=np.array([1.2])
)

print("alpha data:", data.alpha)
print("beta data:", data.beta)

alpha data: BitArray(<shape=(), num_shots=1, num_bits=2>)
beta data: [1.2]

Parameters

• data – Name/value data to place in the data bin.
• shape (ShapeInput) – The leading shape common to all entries in the data bin. This defaults to the trivial leading shape of () that is compatible with all objects.

Raises

• ValueError – If a name overlaps with a method name on this class.
• ValueError – If some value is inconsistent with the provided shape.
