  In this work, we introduce a new concatenation scheme which aims at
protecting information against the occurrence of both computational errors and
quantum erasures. According to our scheme, the internal code must be a quantum
loss-correcting code that does not perform measurements, while the external
code must be a quantum error-correcting code. We illustrate the concatenation
proposed with an example in which one qubit of information is protected against
the occurrence of two erasures and one computational error.
