Resumen:
We propose a new approach to study the evolution of a quantum state that is
encoded in a system which is continuously subject to the operations required
to implement a quantum error correcting code. In the limit of continuous error
correction we introduce a Markovian master equation that includes the effects of:
a) Hamiltonian evolution, b) errors caused by the interaction with an environment
and c) error?correcting operations. The master equation is formally presented for
all stabilizer codes and its solution is analyzed for the simplest such code
