Module Contents

class AttachmentScope

Bases: str, enum.Enum

Scope describing where a noise or perturbation can be attached.

Initialize self. See help(type(self)) for accurate signature.

GLOBAL = 'global'

PER_QUBIT = 'per_qubit'

PER_GATE_TYPE = 'per_gate_type'

PER_GATE_TYPE_PER_QUBIT = 'per_gate_type_per_qubit'

class HasAllowedScopes

Bases: Protocol

Protocol for types that declare their allowed attachment scopes.

classmethod allowed_scopes() → frozenset[AttachmentScope]

Return the attachment scopes supported by the type.

Returns:

The set of scopes where the type can be attached.

class SupportsTimeDerivedKraus

Bases: Protocol

Protocol for types that produce duration-dependent Kraus channels.

as_kraus_from_duration(*, duration: float) → qilisdk.noise.representations.KrausChannel

Return a Kraus channel derived for a specific duration.

Parameters:

duration (float) – Duration over which the noise acts.

Returns:

The Kraus channel for the given duration.

class SupportsStaticKraus

Bases: Protocol

Protocol for types that expose a fixed Kraus channel.

as_kraus() → qilisdk.noise.representations.KrausChannel

Return the static Kraus channel for this noise.

Returns:

The Kraus channel representation.

class SupportsStaticLindblad

Bases: Protocol

Protocol for types that expose a fixed Lindblad generator.

as_lindblad() → qilisdk.noise.representations.LindbladGenerator

Return the Lindblad generator for this noise.

Returns:

The Lindblad generator representation.

class SupportsTimeDerivedLindblad

Bases: Protocol

Protocol for types that expose a Lindblad generator derived from time.

as_lindblad_from_duration(*, duration: float) → qilisdk.noise.representations.LindbladGenerator

Return the Lindblad generator for this noise.

Parameters:

duration (float) – Duration over which the noise acts.

Returns:

The Lindblad generator representation.
