Modes and states in quantum optics

C Fabre, N Treps - Reviews of Modern Physics, 2020 - APS
A few decades ago, quantum optics stood out as a new domain of physics by exhibiting
states of light with no classical equivalent. The first investigations concerned single photons …

This article reviews the extraordinary features of quantum information predicted by the
quantum formalism, which, combined with the development of modern quantum …

Observation of one-way Einstein–Podolsky–Rosen steering

V Händchen, T Eberle, S Steinlechner… - Nature …, 2012 - nature.com
The distinctive non-classical features of quantum physics were first discussed in the seminal

Quantum communication with Gaussian channels of zero quantum capacity

G Smith, JA Smolin, J Yard - Nature Photonics, 2011 - nature.com
As with classical information,, error-correcting codes enable reliable transmission of
quantum information through noisy or lossy channels,,. In contrast to classical theory …

Multipartite entanglement of a two-separable state

S Gerke, J Sperling, W Vogel, Y Cai, J Roslund… - Physical review …, 2016 - APS
We consider a six-partite, continuous-variable quantum state that we have effectively
generated by the parametric down-conversion of a femtosecond frequency comb. We show …

Complementarity reveals bound entanglement of two twisted photons

BC Hiesmayr, W Löffler - New journal of physics, 2013 - iopscience.iop.org
