qml.devices.qubit.sample_state

sample_state(state, shots, is_state_batched=False, wires=None, rng=None, prng_key=None)

Returns a series of samples of a state.

Parameters

• state (array[complex]) – A state vector to be sampled

• shots (int) – The number of samples to take

• is_state_batched (bool) – whether the state is batched or not

• wires (Sequence[int]) – The wires to sample

• rng (Union[None, int, array_like[int], SeedSequence, BitGenerator, Generator]) – A seed-like parameter matching that of seed for numpy.random.default_rng. If no value is provided, a default RNG will be used

• prng_key (Optional[jax.random.PRNGKey]) – An optional jax.random.PRNGKey. This is the key to the JAX pseudo random number generator. Only for simulation using JAX.

Returns

Sample values of the shape (shots, num_wires)

Return type

ndarray[int]
