Testing spectral filters as Gaussian quantum optical channels
K. Laiho, A. Christ, K. N. Cassemiro +1
We experimentally investigate the mode characteristics of multimode radiation fields propagating through frequency dependent Gaussian channels. After manipulating the twin beams em…
Probing multimode squeezing with correlation functions
Andreas Christ, Kaisa Laiho, Andreas Eckstein +2
Broadband multimode squeezers constitute a powerful quantum resource with promising potential for different applications in quantum information technologies such as information cod…
A bright, pulsed two-mode squeezer
Andreas Eckstein, Andreas Christ, Peter J. Mosley +1
We report the realization of a bright ultrafast two-mode squeezer based on type II parametric downconversion (PDC) in periodically poled (PP-KTP) waveguides. It…
