In order to store quantum information we need to protect it from decoherence, either passively (with a suitable energy landscape) or actively (using error correcting methods). In the first case it is well know that the confinement of excitations is crucial for a successful protection. I will discuss how also in the active error correction setting confinement can play a role, resulting in an unsuspected connection between the two scenarios.
