bloqade.lanes.rewrite.move2squin.noise.NoiseModelABC

Bases: abc.ABC

Abstract base class for noise models used during move-to-squin compilation.

class NoiseModelABC

Public import paths

• from bloqade.lanes import NoiseModelABC
• from bloqade.lanes.compile import NoiseModelABC
• from bloqade.lanes.transform import NoiseModelABC
• from bloqade.lanes.rewrite.move2squin import NoiseModelABC

This is the physical noise model interface. It defines noise kernels for physical operations (lane moves, CZ gates, idle periods, local/global rotations). Methods that return None indicate no noise is inserted for that operation.

For logical compilation that also needs initialization kernels, see LogicalNoiseModelABC.

methodget_global_rz_noise¶source

bloqade.lanes.rewrite.move2squin.noise.NoiseModelABC.get_global_rz_noise

Signature

def get_global_rz_noise() -> ir.Method[[ilist.IList[qubit.Qubit, Any], float], None] | None

Return the noise kernel for global Rz rotations, or None.

Returns

ir.Method[[ilist.IList[qubit.Qubit, Any], float], None] | None

source

methodget_local_rz_noise¶source

bloqade.lanes.rewrite.move2squin.noise.NoiseModelABC.get_local_rz_noise

Signature

def get_local_rz_noise(locations: Sequence[LocationAddress]) -> ir.Method[[ilist.IList[qubit.Qubit, Any], float], None] | None

Return the noise kernel for local Rz rotations, or None.

Parameters

Name	Type	Description
locations	Sequence[LocationAddress]

Returns

ir.Method[[ilist.IList[qubit.Qubit, Any], float], None] | None

methodget_global_r_noise¶source

bloqade.lanes.rewrite.move2squin.noise.NoiseModelABC.get_global_r_noise

Signature

def get_global_r_noise() -> ir.Method[[ilist.IList[qubit.Qubit, Any], float, float], None] | None

Return the noise kernel for global R rotations, or None.

Returns

ir.Method[[ilist.IList[qubit.Qubit, Any], float, float], None] | None

source

methodget_local_r_noise¶source

bloqade.lanes.rewrite.move2squin.noise.NoiseModelABC.get_local_r_noise

Signature

def get_local_r_noise(locations: Sequence[LocationAddress]) -> ir.Method[[ilist.IList[qubit.Qubit, Any], float, float], None] | None

Return the noise kernel for local R rotations, or None.

Parameters

Name	Type	Description
locations	Sequence[LocationAddress]

Returns

ir.Method[[ilist.IList[qubit.Qubit, Any], float, float], None] | None

methodget_logical_initialize¶source

bloqade.lanes.rewrite.move2squin.noise.NoiseModelABC.get_logical_initialize

Signature

def get_logical_initialize() -> tuple[ir.Method[[float, float, float, ilist.IList[qubit.Qubit, Any]], None] | None, ir.Method[[float, float, float, ilist.IList[qubit.Qubit, Any]], None] | None]

Return (clean_kernel, noisy_kernel) for logical initialization.

The clean kernel is used by InsertGates for the noiseless initialization. The noisy kernel, if not None, is invoked by InsertNoise after initialization to apply initialization noise.

Returns (None, None) by default, meaning no initialization is provided by the noise model.

Returns

tuple[ir.Method[[float, float, float, ilist.IList[qubit.Qubit, Any]], None] | None, ir.Method[[float, float, float, ilist.IList[qubit.Qubit, Any]], None] | None]

methodget_lane_noise¶source

bloqade.lanes.rewrite.move2squin.noise.NoiseModelABC.get_lane_noise

def get_lane_noise(lane: LaneAddress) -> ir.Method[[qubit.Qubit], None]

Return the noise kernel applied to a qubit after a lane move.

Parameters

Name	Type	Description
lane	LaneAddress

Returns

ir.Method[[qubit.Qubit], None]

bloqade.lanes.rewrite.move2squin.noise.NoiseModelABC.get_bus_idle_noise

Signature

def get_bus_idle_noise(move_type: MoveType, bus_id: int) -> ir.Method[[ilist.IList[qubit.Qubit, Any]], None]
