MultivariateUniformDistribution
class MultivariateUniformDistribution(num_qubits, low=None, high=None)
The Multivariate Uniform Distribution.
Although this just results in a Hadamard gate on all involved qubits, the lower and upper bounds and the assignment of the qubits to the different dimensions is important if used in a particular application.
Parameters
- num_qubits (
Union[List[int],ndarray]) – List with the number of qubits per dimension - low (
Union[List[float],ndarray,None]) – List with the lower bounds per dimension, set to 0 for each dimension if None - high (
Union[List[float],ndarray,None]) – List with the upper bounds per dimension, set to 1 for each dimension if None
