- <p>This computational notebook presents a toy quantum error-correction simulation for studying coherent non-Markovian noise in a distance-5 repetition code.</p> <p>The model uses five data qubits and five environment qubits. Each data qubit is coupled to its own environment qubit through a coherent system-environment interaction, and the environment is not reset between QEC rounds. This allows memory effects to build up over repeated correction cycles.</p> <p>The notebook compares two descriptions of the same noisy QEC experiment:</p> <p>1. full coherent non-Markovian system-environment evolution, and<br>2. a Pauli-twirled / SPP-style stochastic Pauli baseline.</p> <p>The main quantity studied is the logical failure probability as a function of coupling strength. The aim is to test the limits of Pauli-twirled or SPP-style approximations by checking when coherent memory effects change the logical error rate.</p> <p>This is an exploratory notebook and a first-stage QEC-level toy model before moving to larger surface-code simulations.</p>
