How many logical states for a qubit

Webthat we can compute decoherence rates of a logical qubit encoded in our system in presence of additionnal noise channels introduced in the model; in particular, setting the noise strength to zero, we will see that the intrinsic decoherence rate due to the imperfect stabilization of grid-states is exponentially small in 1= . 2 Stability analysis A physical qubit is a physical device that behaves as a two-state quantum system, used as a component of a computer system.
