Deterministic generation of non-classical states by designed loss and quantum state diagnosis


The primary aim of this project is to develop a realistic scheme for generation of non-classical states of electromagnetic radiation by the artificially designed nonlinear loss. Non-classical, non-Gaussian states are of great demand in quantum informatics and communications. Schemes involving the artificially designed nonlinear loss are potentially able to provide very robust generation of sequence of non-distinguishable state in a well-defined mode. The intention of this project is to investigate in more details existing proposals (especially ones suggested by the author of this project) and develop novel schemes, more stable with respect to linear losses than the previously suggested ones. The other line of the research in frame of this project is the diagnostics and reconstruction of generated non-classical quantum states. The efficient and simple procedures for determination of quantum state parameters, and for diagnostics of non-classicality are of great demand nowadays. Any quantum state generated in practice should be verified, since losses and unexpected noise can strongly distort the state. (AU)
