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…
