Direct Characterization of Quantum Dynamics
... An additional feature of DCQD is that all the required ensemble measurements, for measuring the expectation values of the stabilizer and normalizer operators, can also be performed in a temporal sequence on the same pair of qubits with only one Bell-state generation. This is because at the end of ea ...
