What if quantum errors were the feature, not the bug?

Error correction is usually all-or-nothing: suppress decoherence as hard as possible. This work flips that logic, showing that by randomizing the decoder and recovery steps in a standard error-correction cycle, you can tune the *type* and *rate* of logical errors to match a desired dissipative process. The result is a programmable noise generator that lets quantum hardware simulate open quantum systems—think molecules interacting with a heat bath—without the extra ancilla qubits normally required for that task.
