Abstract

A study was carried out to show that a measurement based on the detection of a small number of atoms from the condensate and measuring their spin structure cannot distinguish between a coherent state and a singlet state. Furthermore, it was illustrated that a spinor Bose-Einstein condensate (BEC) in a singlet state evolves into a coherent state after the measurement.
