collection
Iceberg code
An even-length CSS family with one all-X stabilizer and one all-Z stabilizer. On 2m physical qubits these two independent global parity checks leave 2m-2 logical qubits and detect every weight-one Pauli error. The familiar four-qubit two-logical code is the smallest member, not the whole family.
