Abstract

We propose a test to measure the bosonic quality of particles with respect to physical operations of single-particle addition and subtraction. We apply our test to investigate bosonic properties of composite particles made of an even number of fermions and suggest its experimental implementation. Furthermore, we discuss features of the processes of particle addition and subtraction in terms of optimal quantum operations.
