  • Department of Physics, National University of Singapore, Singapore(Dated: January 10, 2014)We propose a measure of quantumness based on an addition-then-subtraction operation. Wedemonstrate how this measure can distinguish between classical and bosonic particles by investi-gating in detail multi-particle bosonic systems. Experimental schemes implementing this measurefor bosons in all-optical and atom-cavity systems are provided. We also apply this measure tosingle-mode fermionic systems.
