Methods

@classmethod
from_noise_model_like(
    noise: "cirq.NOISE_MODEL_LIKE"
) -> "cirq.NoiseModel"

Transforms an object into a noise model if umambiguously possible.

Args
`noise`	`None`, a `<a href="../../cirq/devices/NoiseModel"><code>cirq.NoiseModel</code></a>`, or a single qubit operation.

Returns
`<a href="../../cirq#NO_NOISE"><code>cirq.NO_NOISE</code></a>` when given `None`, `<a href="../../cirq/devices/ConstantQubitNoiseModel"><code>cirq.ConstantQubitNoiseModel(gate)</code></a>` when given a single qubit gate, or the given value if it is already a `<a href="../../cirq/devices/NoiseModel"><code>cirq.NoiseModel</code></a>`.

Raises
`TypeError`	The input is not a `cirq.NOISE_MODE_LIKE`.

get_default_noise_dict() -> Dict[str, Any]

Returns the current noise parameters

get_op_string(
    cirq_op: cirq.ops.Operation
) -> str

Find the string representation for a given operation

Args
`cirq_op`	one cirq operation

Returns
String representing the gate operations

is_virtual_moment(
    moment: "cirq.Moment"
) -> bool

Returns true iff the given moment is non-empty and all of its operations are virtual.

Moments for which this method returns True should not have additional noise applied to them.

Args
`moment`	`<a href="../../cirq/ops/Moment"><code>cirq.Moment</code></a>` to check for non-virtual operations.

Returns
True if "moment" is non-empty and all operations in "moment" are virtual; false otherwise.

noisy_moment(
    moment: cirq.ops.Moment,
    system_qubits: Sequence[cirq.ops.Qid]
) -> List[cirq.ops.Operation]

Returns a list of noisy moments. The model includes

Depolarizing noise with gate-dependent strength Args: moment: ideal moment system_qubits: List of qubits Returns: List of ideal and noisy moments

noisy_moments(
    moments: "Iterable[cirq.Moment]",
    system_qubits: Sequence['cirq.Qid']
) -> Sequence['cirq.OP_TREE']

Adds possibly stateful noise to a series of moments.

Args
`moments`	The moments to add noise to.
`system_qubits`	A list of all qubits in the system.

Returns
A sequence of OP_TREEs, with the k'th tree corresponding to the noisy operations for the k'th moment.

noisy_operation(
    operation: "cirq.Operation"
) -> "cirq.OP_TREE"

Adds noise to an individual operation.

Args
`operation`	The operation to make noisy.

Returns
An OP_TREE corresponding to the noisy operations implementing the noisy version of the given operation.
