MUARC seminar

Realizing building blocks of photon quantum optics for matter waves is a long-standing goal. We present an efficient source for twin-atom beams, in analogy to parametric down-conversion in non-linear optics. The source shows strong non-classical correlations in the population of the two beams, – 10dB below the classical limit. We also realized an integrated Mach-Zehnder interferometer for matter waves by combining a spatial beam splitter for BEC , a gravity-dependent phase-shifter and a recombined based on a pulsed Josephson tunnel junction. The intrinsic non-linearity of the matter waves leads to number squeezing in the splitting process and to fundamental phase diffusion in the interferometer sequence. We will discuss performance limits towards matter wave metrology.
