Specific term required. The classical shadow protocol requires that an ensemble of unitary transformations define a set of measurements that is “complete” with respect to this technique, meaning that they comprise a “quorum” (15[1])that forms an operator basis. A “quantum” form of this technique reconstructs a quantum state from measurements on an ensemble (15[1])of identical quantum states. The inverse (*) Radon transform (10[1])performs “reconstruction” from this technique, which is the task of estimating (10[1])a multidimensional system from projections. The most common use of Hounsfield units (10[1])is to report (10[1])results from a form of this (-5[1])technique that rotates an X-ray tube around a patient. For 10 points, name this technique that involves imaging via sections (-5[1])and is “computed” in a (10[1])CT (10[1])scan. ■END■ (10[1])
