| contents | We develop an error-corrected quantum computation scheme based on concatenating the five-qubit Laflamme code onto the four-qubit Iceberg code. The approach skates a thin line: it is explicitly not fault tolerant, risking higher logical error rates, and it relies on selective filtering to prepare encoded states for error correction, risking significant overhead. Yet, at realistic simulated noise rates, the scheme is reliable and resource efficient. It forges a practical path toward scalable quantum computation. |
