Syndrome-as-Header: A Quantum Label-Switching Architecture via Uncorrectable Error Injection

IlKwon Sohn, Ju-Bong Kim, Kwangil Bae +2

The paper introduces Syndrome-as-Header (SAH), a quantum label‑switching method that embeds routing information in the error‑syndrome of an encoded quantum payload using uncorrecta…
