Logical operations

Available gates, mechanisms, costs, and provenance.

logical Pauli X and Z representatives transversal verified
Level: Pauli · Cost: one parallel layer on three data qubits: Z on one site in every inner block for logical X, or X across one complete block for logical Z; equivalent representatives follow by stabilizer multiplication
CNOT between two fixed Shor blocks transversal verified
Level: Clifford · Cost: one layer of nine pairwise physical CNOTs; with the declared encoded-basis logical names, the physical arrows point from the logical target block toward the logical control block. Routing, syndrome extraction, and recovery before or after the layer are additional resources.
