Identifying quantumness via addition-then-subtraction operation
arXiv:1212.5338 · doi:10.1103/PhysRevA.88.013806
Abstract
We propose a measure of quantumness based on an addition-then-subtraction operation. We demonstrate how this measure can distinguish between classical and bosonic particles by investigating in detail multi-particle bosonic systems. Experimental schemes implementing this measure for bosons in all-optical and atom-cavity systems are provided. We also apply this measure to single-mode fermionic systems.
