Abstract
We consider the quantum discord in a two-particle spin-1/2 system (dimer) governed by the standard multiple quantum (MQ) Hamiltonian and reveal the relation between the discord and the intensity of the second-order MQ coherence. Since the coherence intensities may be measured in experiment, we obtain a method of detecting the quantum discord in experiment. Comparison of discord and concurrence is represented.
► The expression for the discord in dimer in MQ NMR experiment is derived. ► The relation between the discord and second-order MQ coherence intensity is obtained. ► Second-order MQ NMR coherence intensity may be used to detect the discord.
