tomography
/toʊˈmɒɡrəfi/
Definition
A process of reconstructing or mapping the state of a quantum system by performing multiple measurements on various projections to build a complete picture of its internal properties.
Etymology
The word is derived from the Greek roots 'tomos' (slice or section) and 'graphia' (writing or drawing). It was originally developed in medical contexts like CT scans to create cross-sectional images, a metaphor now applied to reconstructing quantum states.
In the news
In the article, the researchers used quantum tomography as a validation technique to accurately probe and verify the states of the qubits after they were synced by the quantum bath. It allows scientists to look past the binary '0 or 1' collapse caused by measurement to see the underlying superposition.
