    "abstract": "Quantum process tomography is a procedure by which an unknown quantum\noperation can be fully experimentally characterized. We reinterpret Choi\u0027s\nproof of the fact that any completely positive linear map has a Kraus\nrepresentation [Lin. Alg. and App., 10, 1975] as a method for quantum process\ntomography. Furthermore, the analysis for obtaining the Kraus operators are\nparticularly simple in this method.",
