WebbQuantum tomography or quantum state tomography is the process by which a quantum state is reconstructed using measurements on an ensemble of identical quantum states. [1] The source of these states may be any device or system which prepares quantum states either consistently into quantum pure states or otherwise into general mixed states. Webb12 aug. 2024 · Most previous results on compressed process reconstruction reduce the problem to quantum state tomography on the channel's Choi matrix. While this ansatz yields recovery guarantees from an essentially minimal number of measurements, physical implementations of such schemes would typically involve ancillary systems.
