Continuous-variable state moments from randomized homodyne and heterodyne measurements
Michael Tsesmelis, Moritz Straeter, Leong-Chuan Kwek
Continuous-variable (CV) quantum states are naturally characterized by their moments, defined as expectation values of products of single- or multimode ladder operators. Many CV Ha…

Detecting entanglement of non-Gaussian continuous-variable states from single-copy homodyne measurements
Moritz Straeter, Michael Tsesmelis, Leong-Chuan Kwek
The entanglement of Gaussian continuous-variable (CV) states is fully determined by the state's second moments. In contrast, some entangled non-Gaussian states evade every second-m…
