Temporal State Tomography via Quantum Snapshotting the Temporal Quasiprobabilities
Temporal State Tomography (TST) is a new method to reconstruct quantum processes across multiple time instances using temporal quasiprobability distributions (TQDs). The approach unifies reconstructing both density operators and quantum channels into a single framework. It introduces a quantum snapshotting scheme to experimentally obtain these complex distributions, enabling the reconstruction of both static states and dynamical evolutions.
