Gaussian and non-Gaussian multimode entangled states of optical frequency combs (Conference Presentation)
Author(s): Nicolas Treps

Paper Abstract

Optical Gaussian entangled states can be generated deterministically, up to very large number of modes. Furthermore, for nontrivial quantum computation, non-Gaussianity is required, which can be obtained from photon subtraction. We will explore here the controlled generation of multimode graph states from ultrafast optical pulses (optical frequency combs) and parametric down conversion in a synchronously pumped cavity, investigating in particular spectral shaping of the pump. Mode dependent photon subtraction is then implemented through sum-frequency generation, and characterization is performed through frequency resolved homodyne detection. We study the influence of a non Gaussian ingredient on a Gaussian graph state.
