Quantum correlations play vital roles in the quantum features in quantum information processing tasks. Among the measures of quantum correlations, quantum discord (QD) and entanglement of formation (EOF) axe two s...
Suppression of noises is studied for the open-loop-closed-loop (OPCL) coupling systems between the driver and response systems. In OPCL coupling systems, the error signal of noise is found to be suppressed and shows...
