    "abstract": "Decoherence free subspaces (DFS) is a theoretical tool towards experimental\nimplementation of quantum information storage and processing. However, they\nrepresent an experimental challenge, since conditions for their existence are\nvery stringent. This work explores the situation in which a system of $N$\noscillators coupled to a bath of harmonic oscillators is close to satisfy the\nconditions for the existence of DFS. We show, in the Born-Markov limit and for\nsmall deviations from separability and degeneracy conditions, that there are\n{\\emph{weak decoherence subspaces}} which resemble the original notion of DFS.",
