Simplifying the process of detecting genuine multiparticle entanglement

The ability to entangle particles is considered essential for a number of experiments and applications. While we have seen evidence for quantum entanglement, it is still difficult to detect unambiguously. Multiparticle quantum correlations are especially important for work with optical lattices, superconducting qubits and quantum information processing. "Entanglement in large qubit systems is becoming more important," Bastian Jungnitsch tells PhysOrg.com. "Unfortunately, the characterization of multiparticle entanglement is difficult."
