Herein, we present.an approach t. look for t.e best.phenom.non t. m.asure quant.m.correlat.on. t.e syst.m.of t.o isolat.d qubit. each int.ract.ng wit. a single-m.de cavit. was t.eoret.cally creat.d t. st.dy t.e quant.m.correlat.on. Som. of t.e phenom.na, such as t.e quant.m.discord and concurrence, were generat.d t.rough such a syst.m. t.e influences of init.al st.t. purit., qubit.m.t.on, and det.ning param.t.rs were discussed for t.e phenom.na. t.ese param.t.rs for a specific value show t.at.t.e behavior of phenom.na are analogous. It.is int.rest.ng t. m.nt.on t.at.som. values of det.ning undergo a sudden deat. of phenom.na, and t.e quant.m.discord st.ll capt.res t.e qubit. quant.m.correlat.on. We predict.t.at.t.e quant.m.discord m.y be a bet.er m.asure of quant.m.correlat.on t.an concurrence.
