Noise robustness in the detection of non-separable random unitary maps
Chiara Macchiavello, Matteo A. C. Rossi · Physica Scripta · 2013
We briefly review in this paper a recently proposed method to detect the properties of quantum noise processes and quantum channels. We illustrate in detail the method for detecting non-separable random unitary channels and consider, in particular, explicit examples of the CNOT and C-Z gates. We also analyse their robustness in the presence of noise for several quantum noise models.
