Angular-momentum nonclassicality by breaking classical bounds on statistics
Alfredo Luis, Ángel Rivas
We derive simple practical procedures revealing the quantum behavior of angular momentum variables by the violation of classical upper bounds on the statistics. Data analysis is mi…
Sub-Heisenberg estimation of non-random phase-shifts
Ángel Rivas, Alfredo Luis
We provide evidence that the uncertainty in detection of small and deterministic phase-shift deviations from a working point can be lower than the Heisenberg bound, for fixed finit…
Contradictory uncertainty relations
Alfredo Luis
We show within a very simple framework that different measures of fluctuations lead to uncertainty relations resulting in contradictory conclusions. More specifically we focus on T…
Independent nonclassical tests for states and measurements in the same experiment
Alfredo Luis, Ángel Rivas
We show that one single experiment can test simultaneously and independently both the nonclassicality of states and measurements by the violation or fulfillment of classical bounds…
