    "abstract": "We argue that the claimed optimality of a new process tomography method\nsuggested in [quant-ph/0601033] and [quant-ph/0601034] is based on not\ncompletely fair comparison that does not take into account the available\ninformation in an equal way. We also argue that the method is not a new process\ntomography scheme, but rather represents an interesting modification of ancilla\nassisted process tomography method. In our opinion these modifications require\ndeeper understanding and further investigation.",
