Nuclear spin tomography is an application in (human) medicine known from medical institutions. The patient absorbs and re-emits electromagnetic radiation in all directions in space. They are detected and 3D images or 2D slice images are reconstructed from that data. Set in the framework of a fundamental science laboratory, the patient is replaced by a quantum object and the electromagnetic radiation by quantum measurement. The result is a procedure referred to as quantum state tomography. Reconstructing quantum states without post-processing Quantum state tomography is the process of reconstructing - or more precisely completely characterizing - the quantum state of an object as it is emitted by its source, before a possible measurement or interaction with the environment takes place. This technique has become an essential tool in the emerging field of quantum technologies.
