Simplified quantum process tomography
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. WebbDr. Kutsaev is a project leader or PI of many DOE SBIR grants that include RF, accelerator, magnet, THz optics, quantum computing, electronics and software technologies.
