We propose an experimentally feasible scheme to generate nonmaximal entanglement between two atomic ensembles. The degree of entanglement is readily tunable. The scheme involves laser manipulation of atomic ensembles; the setup includes adjustable quarter- and half-wave plates, a beam splitter, polarizing beam splitters, and single-photon detectors, and fits well the state of current experimental technology. Finally, we use the nonmaximally entangled state of ensembles to demonstrate quantum nonlocality by detecting the Clauser–Horne–Shimony–Holt inequality.
