    "abstract": "One of the challenges in quantum information is the demonstration of quantum\ncoherence in the operations of experimental devices. While full quantum process\ntomography can do the job, it is both cumbersome and unintuitive. In this\npresentation, we show that a surprisingly detailed and intuitively accessible\ncharacterization of errors is possible by measuring the error statistics of\nonly two complementary classical operations of a quantum gate.",
