qat.synthopline.linear_synthesis.random_linear_operator(nbqbits)

Generate a random linear operator over nbqbits qbits.

The output operator is generated using \(O(n^2)\) line operations, which, on average, produces operator with high CNOT complexity.

Note

The seed of the generator can be controlled using numpy’s random.seed method.

import numpy as np
from qat.synthopline.linear_synthesis import random_linear_operator

np.random.seed(23)
table = random_linear_operator(10)
print(table)

[[1 0 0 1 1 1 0 0 1 1]
 [1 1 1 1 0 0 1 1 1 1]
 [0 0 1 0 0 0 0 0 0 0]
 [0 1 0 1 0 1 0 0 0 1]
 [0 0 0 0 0 1 0 1 1 1]
 [0 1 1 0 1 1 0 1 0 0]
 [0 1 1 0 0 0 1 1 0 0]
 [0 1 0 1 0 0 1 0 1 1]
 [0 0 0 0 1 0 1 0 1 1]
 [1 0 1 0 0 1 0 1 0 1]]

Parameters

nbqbits (int) – the number of qubits

Returns

a linear operator

Return type

np.ndarray

Note

This method is available as an application in Qaptiva Access.
