Quantum technology of non-classical light

We report on our progress with experiments on synthesis and quantum tomography characterization of highly non-classical states of the light field. Based on our previous work on quantum tomography of the single-photon state we demonstrate how various modifications of the experimental setup lead to an extensive set of new, formerly uninvestigated quantum states of light. This includes displaced Fock states, photonadded states, Schroedinger cat states and many others. These experiments have an ultimate goal of developing a technology of generating arbitrary single-mode quantum-optical states. Among our further aims is applying the prepared single-mode states to implementing quantum teleportation and an elementary quantum gate along the lines of a recent linear-optical quantum computation proposal.
