We compare the sensitivity of Hilbert and Bures distances between two qubits in revealing small perturbations occurring to one of the qubits. We also analyze sensitivity n revealing perturbations to noise parameter of a depolarizing channel.

Abstract
We compare the sensitivity of Hilbert and Bures distances between two qubits in revealing small perturbations occurring to one of the qubits. We also analyze sensitivity n revealing perturbations to noise parameter of a depolarizing channel.
