bloqade.lanes.arch.gemini.logical.upstream.steane7_transversal_map

Signature

def steane7_transversal_map(address: AddressType) -> Iterator[AddressType] | None

Public import paths

• from bloqade.lanes.pipeline.logical import steane7_transversal_map
• from bloqade.lanes.arch.gemini.logical import steane7_transversal_map

Map logical addresses to physical addresses via site expansion.

The Steane [[7,1,3]] code encodes one logical qubit into seven physical qubits. Each logical site expands to 7 physical sites within the same word:

Logical site s → Physical sites s7, s7+1, …, s*7+6

Word ID is preserved. Only expands logical site IDs (0 and 1). Returns None for site IDs >= 2 (already physical / not a logical site).

Parameters

Name	Type	Description
address	AddressType

Returns

Iterator[AddressType] | None
