Detection of quantum channel capacities with few local measurements
We propose a method to detect lower bounds to quantum capacities of a noisy quantum communication channel by means of few measurements and by avoiding full process tomography. We show how the procedure can be easily applied to any finite dimensional system and unknown noisy channels. We test its efficiency by studying its performance for most well known single qubit noisy channels, for the generalised Pauli channel in arbitrary finite dimension and for correlated Pauli and amplitude damping channels acting on two qubits.
