Demonstrating various quantum effects with two entangled laser beams
B. Hage, J. Janoušek, S. Armstrong +5
We report on the preparation of entangled two mode squeezed states of yet unseen quality. Based on a measurement of the covariance matrix we found a violation of the Reid and Drumm…

Direct Sampling of Negative Quasiprobabilities of a Squeezed State
T. Kiesel, W. Vogel, B. Hage +1
Although squeezed states are nonclassical states, so far, their nonclassicality could not be demonstrated by negative quasiprobabilities. In this work we derive pattern functions f…

Photon number discrimination without a photon counter and its application to reconstructing non-Gaussian states
H. M. Chrzanowski, J. Bernu, B. M. Sparkes +5
The non-linearity of a conditional photon-counting measurement can be used to `de-Gaussify' a Gaussian state of light. Here we present and experimentally demonstrate a technique fo…
