-    Implemented :class:`.UniformSuperpositionGate` class, which allows
-    the creation of a uniform superposition state using 
-    the Shukla-Vedula algorithm. This feature facilitates the 
-    creation of quantum circuits that produce a uniform superposition 
-    state :math:`\frac{1}{\sqrt{M}} \sum_{j=0}^{M-1}  |j\rangle`, where 
-    :math:`M` is a positive integer representing the number of 
-    computational basis states with an amplitude of 
-    :math:`\frac{1}{\sqrt{M}}`. This implementation supports the 
-    efficient creation of uniform superposition states, 
-    requiring only :math:`O(\log_2 (M))` qubits and 
-    :math:`O(\log_2 (M))` gates. Usage example:
-
-    .. code-block:: python

-       from qiskit import QuantumCircuit 
-       from qiskit.circuit.library.data_preparation import UniformSuperpositionGate
