A No-Go Theorem for Gaussian Quantum Error Correction
Julien Niset, Jaromir Fiurasek, Nicolas J. Cerf
It is proven that Gaussian operations are of no use for protecting Gaussian states against Gaussian errors in quantum communication protocols. Specifically, we introduce a new quan…
Tests of multimode quantum non-locality with homodyne measurements
Antonio Acín, Nicolas J. Cerf, Alessandro Ferraro +1
We investigate the violation of local realism in Bell tests involving homodyne measurements performed on multimode continuous-variable states. By binning the measurement outcomes i…
Experimentally feasible quantum erasure-correcting code for continuous variables
J. Niset, U. L. Andersen, N. J. Cerf
We devise a scheme that protects quantum coherent states of light from probabilistic losses, thus achieving the first continuous-variable quantum erasure-correcting code. If the oc…
Tight bounds on the concurrence of quantum superpositions
J. Niset, N. J. Cerf
The entanglement content of superpositions of quantum states is investigated based on a measure called {\it concurrence}. Given a bipartite pure state in arbitrary dimension writte…
Multipartite Nonlocality without Entanglement in Many Dimensions
J. Niset, N. J. Cerf
We present a generic method to construct a product basis exhibiting Nonlocality Without Entanglement with parties each holding a system of dimension at least . This basis…
