Relating the Entanglement and Optical Nonclassicality of Multimode States of a Bosonic Quantum Field
Anaelle Hertz, Nicolas J. Cerf, Stephan De Bièvre
The quantum nature of the state of a bosonic quantum field manifests itself in its entanglement, coherence, or optical nonclassicality which are each known to be resources for quan…
Quadrature coherence scale driven fast decoherence of bosonic quantum field states
Anaelle Hertz, Stephan De Bièvre
We introduce, for each state of a bosonic quantum field, its quadrature coherence scale (QCS), a measure of the range of its quadrature coherences. Under coupling to a thermal bath…
Multi-copy uncertainty observable inducing a symplectic-invariant uncertainty relation in position and momentum phase space
Anaelle Hertz, Ognyan Oreshkov, Nicolas J. Cerf
We define an uncertainty observable, acting on several replicas of a continuous-variable bosonic state, whose trivial uncertainty lower bound induces nontrivial phase-space uncerta…
Multidimensional entropic uncertainty relation based on a commutator matrix in position and momentum spaces
Anaelle Hertz, Luc Vanbever, Nicolas J. Cerf
The uncertainty relation for continuous variables due to Byalinicki-Birula and Mycielski expresses the complementarity between two -uples of canonically conjugate variables $(x_…
Higher order nonclassicality from nonlinear coherent states for models with quadratic spectrum
Anaelle Hertz, Sanjib Dey, Véronique Hussin +1
Harmonic oscillator coherent states are well known to be the analogue of classical states. On the other hand, nonlinear and generalised coherent states may possess nonclassical pro…
