Noise robustness in the detection of non separable random unitary maps
arXiv:1310.8233 · doi:10.1088/0031-8949/2013/T153/014044
Abstract
We briefly review a recently proposed method to detect 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 the explicit examples of the CNOT and CZ gates. We analyse their robustness in the presence of noise for several quantum noise models.
