Abstract

The technologies of quantum information and quantum control are rapidly improving, but fall exploitation of their capabiUties reqiures complete characterization and assessment of processes that occur within quantom devices. We present a method for characterizing, with arbitrarily high accuracy, any quantum optical process. Our protocol recovers complete knowledge of the process by studying, via homodyne tomography, its effect on a set of coherent states, i.e. classical fields produced by common laser sources. We demonstrate the capability of our protocol by evaluating and experimentally verifying the effect of a test process on squeezed vacuum.
