Witrynarequired in classical shadow tomography [Huang et al.Nat. Phys. 16, 1050 (2024)]. Unlike previous approaches to shadow tomography, our protocol can be implemented using only global operations, as opposed to qubit-selective logic gates, which makes it particularly well-suited to analog quantum Witryna5 wrz 2024 · Classical shadow tomography is a powerful randomized measurement protocol for predicting many properties of a quantum state with few measurements. Two classical shadow protocols have been extensively studied in the literature: the single-qubit (local) Pauli measurement, which is well suited for predicting local operators but …
