dq.random.ket

ket(key: PRNGKeyArray, shape: tuple[int, ...]) -> QArray

Returns a random ket with unit norm.

Parameters:

• key –

  A PRNG key used as the random key.

• shape (shape of the form (..., n, 1)) –

  Shape of the returned qarray.

Returns:

• (qarray of shape (*shape)) –

  Random ket.

Examples:

>>> key = jax.random.PRNGKey(42)
>>> dq.random.ket(key, (2, 1))
QArray: shape=(2, 1), dims=(2,), dtype=complex64, layout=dense
